The basis of this philosophy is
that there is only One existed, exists and will continue to exist, and that One
is called Brahman. The entire universe with all its contents and variations is
the One (Brahman) only, which is real.
To understand this, there are
three main texts, known as Prasthana Thrayam. These texts are Bhagavad Gita,
Upanishads and Brahma Sutra. Upanishads are known as Sruti Prasthanam and Brahma Sutra is known as Nyaya Prasthanam. Bhagavad Gita is known as Smruti Prasthanam. Bhagavad Gita consists of 700 verses as discussion
between Lord Krishna and Arjuna. In this, the entire philosophy is explained to
the common man, who may not be able to study the other texts (Upanishads) in
detail.
In order to get deeper knowledge,
one has to study the Upanishads. The Upanishads are part of vedas, which is the
basic text. Veda, which means knowledge is considered as (Apurushya) not
written by any man(Rishi). Vedas were classified by Sage Vyasa into four. The
four vedas are, Rig, Yajur, Sama and Atharvana. All these vedas contain
Upanishads. These vedas are generally divided into two parts- the first is
Karma Khanda or Purva Khanda and the
second part is Uttara Khanda. Generally
the word ”Vedanta”refers to upanishads , which are found in vedas but not in the end. "Vedanta" can be translated as end (goal) of Vedas
All will have different types of
goals in their life. These are classified as Artha (material), Kama (wishes), Dharma
(right way of living), and Moksha (self-knowledge). The ways to achieve the
first three are covered in Purva Khanda of the vedas and Vedanta or Uttara
khanda shows the way for moksha.
There are many Upanishads (in all
about 108) and ten are considered as important , for which Shankarachaya had written commentaries. All Upanishads
contain Maha Vakhyam. Maha Vakhyam literally means big sentence, but in Vedanta
, any sentence which gives the relation between Jiva and Paramatma is called
Maha Vakhyam. The most popular maha vakhyams are four , one from each Veda.
There are commentaries on both
parts of Veda. These are known as Mimamsas, the commentary on Purva khanda is
written by Sage Jaimini, disciple of Sage Vyasa and it is called Purva Mimamsa.
This work consists of 12000 slokas. The commentary on Upanishads, (Uttara Mimamsa) written by
Sage Vyasa is called Brahma Sutra –third prasthanam. Brahma sutra consists of
555 slokas, Bhagavad Gita consists of 700 slokas and Upanishads contain many
slokas. But studying Brahma sutra should be undertaken after going through
Bhagavad Gita and Upanishads.
All these vedic texts are in
Samskrit. Even a person who has studied Samskrit language in depth, cannot
understand these texts without the teaching and guidance of an Acharya. The
reason for this is that the same word gives opposite meaning at different
places of these texts. A Samskrit scholar cannot correctly understand these scriptures
from the meaning of the words from the
dictionary. Only a teacher (Acharya) who has learnt the scriptures from a Guru
with tradition ( Parampara) can explain.
