Alpha wave
Alpha
waves are neural
oscillations in the frequency range of 7.5-12.5 Hz
arising from synchronous and coherent (in phase or constructive)
electrical activity of thalamic
pacemaker cells in humans. They are also called Berger's
wave in memory of the founder of EEG.
Alpha waves
are one type of brain
waves detected either by electroencephalography
(EEG) or magnetoencephalography
(MEG) and predominantly originate from the occipital
lobe during wakeful relaxation with closed eyes. Alpha waves are
reduced with open eyes, drowsiness and sleep. Historically, they were
thought to represent the activity of the visual cortex in an idle
state. More recent papers have argued that they inhibit areas of the
cortex not in use, or alternatively that they play an active role in
network coordination and communication. Occipital alpha waves during
periods of eyes closed are the strongest EEG brain signals.
An alpha-like variant called
mu (μ) can be
found over the motor cortex (central scalp) that is reduced with
movement, or the intention to move. Alpha waves do not start to
appear until three years of age.
Biofeedback training
Given the alpha wave's
connection with relaxed mental states, many people have latched onto
the idea of utilizing this state through a technique called
biofeedback training. This technique utilizes EEG to indicate to a
subject or trainer when the subject is in an alpha wave state, which
the subject is then instructed to remain in.
There are several different
prospects of this training that are currently being explored.
Arguably, the most popular one is the use of this training in
meditation.
Zen-trained meditation masters produce noticeably more alpha waves
during meditation. This fact has led to a popular trend of
biofeedback training programs for everyday stress relief.
Psychologists are hoping to
use this technique to help people overcome phobias,
calm down hyperactive
children, and help children with stuttering
problems to relax enough to practice regular speech.
There are other uses of
biofeedback training beyond therapy. Defense Department researchers
are exploring biofeedback as a way of getting captured soldiers to
create alpha waves, potentially foiling enemy lie detectors.
Biofeedback training has also been receiving attention as a possible
way of monitoring attention. It has been theorized that teaching
machines could use biofeedback as a way of monitoring children's
attention, with the appearance of alpha waves signaling a lapse of
attention.
Following this
lapse-of-attention line of thought, a recent study indicates that
alpha waves may be used to predict mistakes. In it, MEGs measured
increases of up to 25% in alpha brain wave activity before mistakes
occurred. This study used common sense: alpha waves indicate
idleness, and mistakes are often made when a person is doing
something automatically, or "on auto-pilot", and not paying
attention to the task they are performing. After the mistake was
noticed by the subject, there was a decrease in alpha waves as the
subject began paying more attention. This study hopes to promote the
use of wireless EEG technology on employees in high-risk fields, such
as air traffic controlling, to monitor alpha wave activity and gauge
the attention level of the employee.

Christian art
About christian art
Early
Christian art survives from dates near the origins of
Christianity. The oldest surviving Christian paintings are from the
site at Megiddo,
dated to around the year 70, and the oldest Christian sculptures are
from sarcophagi,
dating to the beginning of the 2nd century. Until the adoption
of Christianity by Constantine Christian art derived its style
and much of its iconography
from popular Roman
art, but from this point grand Christian buildings built under
imperial patronage brought a need for Christian versions of Roman
elite and official art, of which mosaics
in churches in Rome are the most prominent surviving examples.
During the development of Christian art in the Byzantine
empire (see Byzantine
art), a more abstract aesthetic replaced the naturalism
previously established in Hellenistic
art. This new style was hieratic, meaning its primary purpose was to
convey religious meaning rather than accurately render objects and
people. Realistic perspective, proportions, light and color were
ignored in favor of geometric simplification of forms, reverse
perspective and standardized conventions to portray individuals and
events. The controversy over the use of graven images, the
interpretation of the Second Commandment, and the crisis of Byzantine
Iconoclasm led to a standardization of religious imagery within
the Eastern
Orthodoxy.
The Renaissance saw an increase in monumental secular works, but
until the Protestant
Reformation Christian art continued to be produced in great
quantities, both for churches and clergy and for the laity. During
this time, Michelangelo
Buonarroti painted the Sistine
Chapel and carved the famous Pietà,
Gianlorenzo
Bernini created the massive columns in St.
Peter's Basilica, and Leonardo
da Vinci painted the Last
Supper. The Reformation had a huge
effect on Christian art, rapidly bringing the production of
public Christian art to a virtual halt in Protestant countries, and
causing the destruction of most of the art that already existed.
As a secular, non-sectarian, universal
notion of art arose in 19th century Western Europe, secular artists
occasionally treated Christian themes (Bouguereau,
Manet) — but only
rarely was a Christian artist included in the historical canon (such
as Rouault
or Stanley
Spencer). However many modern artists such as Eric
Gill, Marc
Chagall, Henri
Matisse, Jacob
Epstein, Elizabeth
Frink and Graham
Sutherland have produced well-known works of art for churches.
Since the advent of printing, the sale
of reproductions of pious works has been a major element of popular
Christian culture. In the nineteenth century, this included genre
painters such as Mihály
Munkácsy. The invention of color lithography led to broad
circulation of holy
cards. In the modern era, companies specializing in modern
commercial Christian artists such as Thomas
Blackshear and Thomas
Kinkade, although widely regarded in the fine art world as
kitsch,
have been very successful.
The last part of the 20th and the first part of the 21st century
have seen a focused effort by artists who claim faith in Christ to
re-establish art with themes that revolve around faith, Christ, God,
the Church, the Bible and other classic Christian themes as worthy of
respect by the secular art world. Artists such as Makoto
Fujimura have had significant influence both in sacred and
secular arts. Other notable artists include Larry
D. Alexander, Gary P. Bergel, Carlos Cazares, Bruce Herman,
Deborah Sokolove, and John
August Swanson.
Geometric abstraction
About geometric abstraction
Geometric
abstraction is a form of abstract
art based on the use of geometric forms sometimes, though not
always, placed in non-illusionistic
space and combined into non-objective (non-representational)
compositions. Throughout 20th-century art historical discourse,
critics and artists working within the reductive
or pure strains of abstraction have often suggested that geometric
abstraction represents the height of a non-objective art practice,
which necessarily stresses or calls attention to the root plasticity
and two-dimensionality of painting as an artistic medium. Thus, it
has been suggested that geometric abstraction might function as a
solution to problems concerning the need for modernist painting to
reject the illusionistic practices of the past while addressing the
inherently two dimensional nature of the picture plane as well as the
canvas functioning as its support. Wassily
Kandinsky, one of the forerunners of pure non-objective painting,
was among the first modern artists to explore this geometric approach
in his abstract work. Other examples of pioneer abstractionists such
as Kasimir
Malevich and Piet
Mondrian have also embraced this approach towards abstract
painting.
However, geometric abstraction cannot
only be seen as an invention of 20th century avant-garde
artists or movements. It is present among many cultures throughout
history both as decorative motifs and as art pieces themselves.
Islamic art,
in its prohibition of depicting religious figures, is a prime example
of this geometric pattern-based art, which existed centuries before
the movement in Europe and in many ways influenced this Western
school. Aligned with and often used in the architecture of Islamic
civilations spanning the 7th century-20th century, geometric patterns
were used to visually connect spirituality with science and art, both
of which were key to Islamic thought of the time.
Abstract art has also historically been likened to music
in its ability to convey emotional or expressive feelings and ideas
without reliance upon or reference to recognizable objective forms
already existent in reality. Wassily
Kandinsky has discussed this connection between music and
painting, as well as how the practice of classical composition had
influenced his work, at length in his seminal essay Concerning the
Spiritual in Art.
Expressionist abstract painting, as practiced by artists such as
Jackson
Pollock, Franz
Kline, Clyfford
Still, and Wols,
represents the opposite of geometric abstraction.
Abstract art
About abstract art
Abstract art uses a visual
language of form, color and line to create a composition which
may exist with a degree of independence from visual references in the
world.
Western art
had been, from the Renaissance
up to the middle of the 19th century, underpinned by the logic of
perspective
and an attempt to reproduce an illusion of visible reality. The arts
of cultures other than the European had become accessible and showed
alternative ways of describing visual experience to the artist. By
the end of the 19th century many artists felt a need to create a new
kind of art which would encompass the fundamental changes taking
place in technology, science and philosophy. The sources from which
individual artists drew their theoretical arguments were diverse, and
reflected the social and intellectual preoccupations in all areas of
Western culture at that time.
Abstract art, nonfigurative art, nonobjective art, and
nonrepresentational art are loosely related terms. They are similar,
but perhaps not of identical meaning.
Abstraction indicates a departure from reality in depiction of
imagery in art. This
departure from accurate representation can be slight, partial, or
complete. Abstraction exists along a continuum. Even art that aims
for verisimilitude of the highest degree can be said to be abstract,
at least theoretically, since perfect representation is likely to be
exceedingly elusive. Artwork which takes liberties, altering for
instance color and form in ways that are conspicuous, can be said to
be partially abstract. Total abstraction bears no trace of any
reference to anything recognizable. In geometric
abstraction, for instance, one is unlikely to find references to
naturalistic entities. Figurative
art and total abstraction are almost mutually
exclusive. But figurative
and representational
(or realistic)
art often contains partial abstraction.
Both geometric
abstraction and lyrical
abstraction are often totally abstract. Among the very numerous
art movements
that embody partial abstraction would be for instance fauvism
in which color is conspicuously and deliberately altered vis-a-vis
reality, and cubism,
which blatantly alters the forms of the real life entities
depicted.
Osho quotes
Doubt Needs Great Courage
"Doubt
needs great courage because you will be doubting everything possible.
You will be surrounded by all kinds of doubts. All consoling beliefs
will be taken away, beliefs which gave you a certain confidence, a
certain stability, a certain feeling that you belong to a big
tradition, a well-respected religion of holy scriptures, messiahs,
representatives of God.
"You had all these things surrounding you. They gave you a cozy feeling that you are not alone. I am trying to do just this: cut away everything that gives you a false, cozy feeling and that keeps you dozing all your life.
"Belief is the opium which all the religions have been giving you in good doses. I am trying to destroy your addiction to the opium. My whole effort is to leave you alone."

Osho quotes
The Ego Is a Puzzle
"The ego is a puzzle. It is something like
darkness – which you can see, which you can feel, which can
obstruct your way but which does not exist. It has no positivity. It
is simply an absence, an absence of light. The ego does not exist –
how can you surrender it? The ego is only an absence of
awareness."
"You cannot surrender ego, because it does not exist. You can bring a little awareness, a little consciousness, a little light. Forget completely about the ego; concentrate totally on bringing alertness into your being. And the moment your consciousness has become a flame, concentrated, you will not be able to find the ego."

Osho quotes
A Meditator Needs No Personal
Guidance
"If you can become just your own self, if you can
blossom into your intrinsic nature, then only you will have
blissfulness – a peace which cannot be expressed in words, and a
certain poetry to your being; a certain dance to your being, because
you will be in tune with existence. To be in tune with yourself is
the only way to be in tune with existence. Nobody needs personal
guidance, because all personal guidance is a beautiful name for
dependence on somebody and he is going to distort you."
"A meditator needs no personal guidance. A meditator, on the contrary, needs only one thing: the atmosphere of meditation. He needs other meditators; he needs to be surrounded by other meditators. Because whatever goes on happening within us is not only within us, it affects people who are close by. In this communion people are at different stages of meditation. To meditate with these people, just to sit silently with these people, and you will be pulled more and more towards your own intrinsic potentiality."

Symbolism
Mahayana symbolism
In Mahayana,
Buddhist figures and sacred objects leaned towards esoteric and
symbolic meaning. The Mudras
are a series of symbolic hand gestures describing the actions of the
characters represented in only the most interesting Buddhist
art. Many images also function as mandalas.
Mahayana and Vajrayana Buddhist art
frequently makes use of a particular set of eight auspicious symbols,
ashtamangala,
in domestic and public art. These symbols have spread with Buddhism
to the art of many cultures, including Indian, Tibetan, Nepalese, and
Chinese art.
These symbols are:
- Lotus flower. Representing purity and enlightenment.
- Endless knot, or, the Mandala. Representing eternal harmony.
- Golden Fish pair. Representing conjugal happiness and freedom.
- Victory Banner. Representing a victorious battle.
- Wheel of Dharma or Chamaru in Nepali Buddhism. Representing knowledge.
- Treasure Vase. Representing inexhaustible treasure and wealth.
- Parasol. Representing the crown, and protection from the elements.
- Conch
shell. Representing the thoughts of the Buddha.

About the color indigo
The Color Indigo
The
color indigo is the color of intuition and perception and is helpful in
opening the third eye. It promotes deep concentration during times of
introspection and meditation, helping you achieve deeper levels of
consciousness. It is a color which relates to the "New Age" - the
ability to use the Higher Mind to see beyond the normal senses with
great powers of perception. It relies on intuition rather than gut
feeling.
Indigo is a deep midnight blue. It is a combination of deep blue and violet and holds the attributes of both these colors.
Service
to humanity is one of the strengths of the color indigo. Powerful and
dignified, indigo conveys integrity and deep sincerity.
The
color meaning of indigo reflects great devotion, wisdom and justice
along with fairness and impartiality. It is a defender of people's
rights to the end.
Structure
creates identity and meaning for indigo. In fact an indigo person
cannot function without structure - it throws them right off balance.
Organization is very important to them and they can be quite inflexible
when it comes to order in their lives.
Indigo
loves rituals and traditions, religion and the institutional system,
conforming to things that have worked in the past while planning for the
future.
Indigo
stimulates right brain or creative activity and helps with spatial
skills. It is a dramatic color relating to the world of the theater,
which, during times of stress becomes the drama queen, making a mountain
out of a molehill!
The
negative color meaning of indigo relates to fanaticism and addiction.
Its addiction encompasses everything from a need for recognized
qualifications to a need for illegal drugs, from the workaholic to the
religious fanatic.
Indigo can be narrow-minded, intolerant and prejudiced.
Positive and Negative Traits of Indigo
Positive keywords
include integrity and sincerity, structure and regulations, highly
responsible, idealism, obedience, highly intuitive, practical visionary,
faithful, devotion to the truth and selflessness.
Negative keywords
include being fanatical, judgmental, impractical, intolerant and
inconsiderate, depressed, fearful, self-righteous, a conformist,
addictive, bigoted and avoiding conflict.
The Color Indigo Represents:
Intuition - use it to assist in accessing intuitive abilities - it is the first step to higher spiritual knowledge
Integrity - and deep sincerity are qualities of indigo
Structure and Order-a good colour to use in restructuring aspects of your life or business
Wisdom - an inner knowingness and awareness - spiritual wisdom rather than the wisdom of the intellect
Effects of The Color Indigo:
Introspection - promotes deep concentration during times of introspection and meditation - can lead to feelings of being spaced out.
Idealistic - an ability to plan for the future.
Addiction -
can support an addictive personality into maintaining their addictions -
don't use it if you are trying to overcome an addiction - it is
associated with the religious fanatic - the colour of the workaholic who
thinks they are indispensable - can also be related to those who are
addicted to getting qualifications.
The Dramatist - relates to the acting profession - can cause people to 'make a mountain out of a molehill'.
Conformity - a love of ritual - conformity to the things that have worked in the past, not just for the sake of conforming.
