Story of Jada Bharata and his teachings can be found in the Srimad Bhagavad Purana
It is the mind of man which causes him either to fall into
the morass called samsara or to find freedom from it. It is the mind which
should be subdued.
When the mind is tainted with the three gunas – Sattva,
Rajas and Tamas its path is set in the world of objects. It will have to keep
on performing actions, good or bad: and the cycle of births and deaths will be
endless.
Mind will acquire desires and according to the desires, its
progress will be towards the higher or towards the lower, as the case may be.
Pleasure and pain will affect the life of man and there will
be no end to it. So long as the mind is attached to the things of the world it
can never glow on its own accord.
The real ‘I’ in me has absolutely no connection with this so-called body of mine: and insults to this body or injustices heaped on this body do not affect ‘me’ in the least.
The words are meaningless considering that ‘I’ am formless and the qualification ‘big’ and ‘small,’ ‘lean’ and ‘fat’ do not apply to it. These words are for describing the body, the home of the ‘Atman’ and ‘not the Atman.’
Fatness or leanness, disease of the mind and the body, hunger, thirst, fear, quarrelsomeness, desire, old age, sleep, lust, avarice, pain: all these affect one who thinks that he has a body and not men who knows the Truth about myself. This body is short-lived, limited, while ‘I’ am endless, eternal.
