In the sixth chapter of the Bhagavad-gita Lord Shri Krishna extols the virtues of the yogi (seeker) who is able to constantly abide in the knowledge of the Self. Shri Krishna begins by recapitulating the teachings of the previous chapter where he tells Arjuna that the seeker is one who has renounced the fruits of the actions and not the actions themselves. This allows the mind to constantly engage with the Self, aided through the practice of meditation.
For successfully practicing meditation, Shri Krishna gives detailed guidance as to location, posture and method. He also advocates the practice of moderation in daily habits to allow the steady transcendence of the mind into the higher. Shri Krishna then goes to clarify the doubts Arjuna has as to whether the mind – which is by nature restless – can be made single pointed; and what is the fate of those who fail to realise the Self in spite of their faith and efforts.
Shri Krishna concludes by proclaiming, that of all the seekers, the one who is liberated while living is the best among seekers.
