In plain words
The fruit gained in it is to be found in nothing else. We must keep such a Name of God safe in our hearts. Carry out your duties that belong to the world! You need not give up anything. But you must give up the feeling that you are a man. You are not a man. The body is a bush-coat you have put on. How many such bush-coats you have changed! It is not this. You are grieving over this body.
We must drive away the bad qualities in us
You are not the body. ‘I am God. I am Brahman. ‘Ahaṃbrahmasmi’: see that you do not forget this even in a dream.’ All are embodiments of Brahman! For Brahman there is no second thing at all. ‘Ekameva advitīyaṃ brahma.’ Not two, only one. Having attained such a principle of Brahman, if we still live in such littleness, then truly
Is there anything beyond what is written on the forehead, though one grieves for a hundred years? However much one studies, however one may live, the mean man does not give up his bad qualities; study on and on, and it is only argument and debate; he never attains full Jñāna.
Why study and study this physical, worldly, material, impermanent, transient learning, only to die? You must study the learning that knows no death. Who in this world is the blind man? ‘The one who has learning and yet does not give up his bad qualities is blind,’ they said. When you have learning, you must use it in the right way. You must push bad qualities far away. That is tyāga. What is tyāga? It is not leaving home and hearth, wife and children, property and possessions.
Giving up the evil feelings in the mind, forgetting wickedness and unrest: the giving up of such qualities is tyāga; that alone is true yoga.
