Sutra 3 of Samadhi Pada

Sutra 3: "Tadha drushtuh swarupe avasthanam"

The meaning of this Sutra is 'Then man abides in his real nature.'

When the lake of the mind becomes clear and still, man knows himself as he really is, always was and always will be. He knows that he is the Atman. His personality, his mistaken belief in himself as separate, unique individual, disappears. His body is only a outer covering, a coat or a mask, which he can assume or lay aside as he chooses. Such a man is known as a free, illuminated soul.

For all these things to happen, first thing needed is Yoga of getting Sadguru and Satsanga. Then by doing Sadhana and Seva, one can attain Moksha. If we observe our thought-wave consciously, that disappears automatically. Then there will be silence in the mind. Thats is the state of bliss and awareness. With the knowledge of seer and seen, we can understand the Atman in each and every living beings. Then this mind becomes only slave for that Atman. We can use whenever we want and keep aside when it is not needed. Now mind identifies with the Atman rather than this body. When this happens, for whom and where there is a bondage? so we are liberated.

So be watchful with awareness, of your thoughts. Be aware of your vasanas. Know that which is real and unreal. Then starts the real life.
