The Bhagavad-gita is the famous
philosophical discourse that took place between Lord Krishna and the warrior
Arjuna, just before the onset of the great Bharata War. Although widely
published and read by itself, the Bhagavad-gita originally appears as an
episode in the Sixth Book of the Mahabharata . In this treatise of 700
verses, Lord Krishna systematically surveys the major Vedic dharmas and
shows how each directs a person toward the ultimate conclusion, the "most
confidential of all knowledge." He analyzes the performance of
sacrifices and the worship of demigods; He discusses the yogas of work,
meditation, and knowledge. In each case, Krishna shows how it leads to the "most
secrets of all secrets, " pure loving devotional service to God. "Always
think of Me and become My devotee. Worship Me and offer you homage unto Me."
This, Krishna says is "the most confidential part of knowledge."

The
Gita is the cream of the Vedas and the essence of the soul-elevating
Upanishads. It is a universal scripture applicable to people of all
temperaments and for all times. It is a wonderful book with sublime thoughts
and practical instructions on Yoga, Devotion, Vedanta and Action. It is
profound in thought and sublime in heights of vision. It brings peace and
solace to souls that are afflicted by the three fires of mortal existence,
namely, afflictions caused by one's own body (disease etc), those caused by
beings around one (e.g. wild animals, snakes etc.), and those caused by the
gods (natural disasters, earth-quakes, floods etc).
It contains the advice given by Sri Krishna about the duties of life as
well as spiritual obligations. Sin arises not from the nature of the work
itself but from the disposition with which the work is performed. When it is
performed without attachment to the result, it cannot tarnish the soul and
impede its quest. True Yoga consists in the acquisition of experience and
the passage through life in harmony with the ultimate laws of equanimity,
non-attachment to the fruits of action, and faith in the pervasiveness of
the Supreme Spirit. Absorption in that Spirit can be attained along several
paths; and no path is to be preferred exclusively and none to be disdained.
The Gita emphasizes the importance of knowledge, charity, penance and
worship, and does not decry life as evil.
