Tukaram, Poem 1085

If a Vedantin rejects the existence of his own soul, he is guilty of slaying his teacher; the lesson that was taught him is in vain. That which was whispered in his ear he proclaims to be his own shape. If he still harbours enmity to created things, then his knowledge of Brahma has been stolen from him. If he repeats the words he has been taught, but nourishes self-will and anger and speaks the language of praise or censure, then, says Tuka, he wastes his speech.
