For 30,000 years at least, since the emergence
of our species on earth, man has struggled to understand truth. The self is the
agent of experience and action says Nayaya, one of
six systems of Indian thought that has engaged with the question. It is the
knower,enjoyer, and actor. Its body is the organ of knowledge feeling and
action.
What is knowledge? What is life? The pundits
do not agree on a definition that is work-in-progress yet.
The vaisesika [of the six knowledge systems]
regards life as a particular kind of effort or volition of
self (jivanayonipriyatna). Inhalation, exhalation and the like are its
actions. They are due to the vital efforts of the self.
There is no permanent self says the Buddhist.
A person is a mind body complex, an aggregate of thirty two
kinds of organic matter and five constituent elements of being, outward form
(rupa), feelings (vedana), ideas (samjana), dispositions (samskara) and
consciousness (vijnana). There is no permanent ego or self. The self here is
equated with ego.
The samkhya [knowledge system] regards the
body, the sense organs, mind (manas), intellect (buddhi), and egoism (ahamkar)
as the evolutes of prakriti constituted of sattava, rajas and
tamas.There is interaction between mind and body in perception and volition but
there is no interaction between self and body or mind. The self is
conscious. The mind is unconscious.
According to Jaina the self (jiva) and the
not-self (ajiva) are two entirely different substances. The
former is conscious, incorporeal and immaterial, while the latter is
unconscious, corporeal and material. Matter (pudgala) is not-self. Every
embodied self (samsara jiva) has a soul and body.
The advaita Vedanta [knowledge system] regards
the gross body as composed of of five elements. It is the instrument of
waking experience. The five external sense organs are produced by the five
quintipuled elements. The auditory organ is produced by ether, the tactual
organ by air, the visual organ by light, the gustatory organ by water, and the
olfactory organ by earth. The four internal organs mind (manas) intellect
(buddhi) egoism (ahamakara) and memory (citta) are produced by the five elements collectively with a
predominance of sattava.
The five motor organs the vocal organ, the
prehensive organ, the locomotive organ, the excretory organ, and the generative
organ are produced by the five elements with a predominance of rajas. The organs
themselves are insentient, producing their
effect under the guidance of the conscious self. The five vital airs " prana, apana,
vyana, udana and samana are produced by the five elements collectively
with a predominance of rajas.
According to sankhya, life is not physical
(bhautika) force but the common function of all sense organs. It is sustained
by the powers of the sense organs. The five kinds of vital forces
รข€" prana, apana, udhana, samana and vyana " are the modes of
internal organs [ manas, buddhi,ahamkara]. They are airs because of their motions.
The five vital forces are the common functions of the sense organs.
Samkara considers the five vital forces to be
the different modes of one common life. Prana is the air
that is inhaled. Apana is the air that is exhaled. Vyana is the air that pervades the body.
Udana resides in the throat. It is the air that is belched out. Samana is the
air that resides in the intestines and digests food and drink.
The Advaita Vedanta gives a materialistic view
of the nature and origin of life. The Samkhya gives an
idealistic view tending towards the materialistic because it regards the external
and internal organs as evolutes of prakriti or primal matter. The Vaisesika takes an idealist view as it traces
life to a voilition of self.
The Prapariscara Tantra [knowledge system]
describes ten vital forces. Prana courses upward. Apansa
courses downward. Samana assimilatesfood. Vyana distributes the chyle
(rasa) all over the body. Udana
accompanies prana (life) and and produces
movement of the eyes. Naga is the cause of belching. Kurma is the cause of
opening the eyes.Krkara is the cause of hunger. Devdatta is the cause of yawining.
Dhananjaya causes various sounds.
As we can see knowledge is a variable across
knowledge systems, none of which can seemingly claim
infaliability.
Sri Aurobindo however points out, "All knowledge lies
within" . It can be accessed by anyone who has purified the lower modes of
knowing of all its grossness through the yogic
discipline.
