Vedanta does not want you to renounce the world. It wants you to change your mental attitude and give up this false, illusory 'I-ness' and 'mine-ness'. The snake charmer removes only the two poisonous fangs of the cobra. The snake remains the same. It hisses, raises its hood and shows its fangs. In fact, it does everything as before. The snake charmer has changed his mental attitude towards the snake. He has a feeling now that it has no poisonous fangs. Even so, you must remove the two poisonous fangs of the mind, namely, 'I-ness' and 'mine-ness' only. Then you can allow the mind to go wherever it likes. Then you will always have the feeling of the presence of God.
You must also renounce the attachment to renunciation, which is very deep-rooted. You must renounce the idea: "I have renounced everything; I am a great renunciate". This attachment of aspirants is a greater evil than that of the householders: "I am a landlord; I am a brahmana, etc."
Not by shaving the head, not by dress, not by egoistic action is liberation to be attained. He who possesses wisdom is a real sanyasin (monk). Wisdom is the sign of a sanyasin. The wooden staff does not make a sanyasin. He is the real sanyasin of wisdom who is conscious of his absolute nature even in his dreams just as he is during the waking period. He is the greatest knower of Brahman. He is the greatest of sanyasins.
Perfect renunciation is born of discrimination. Dispassion should not be mild and half-hearted. It should be a burning flame of disgust for everything that is seen and that is not seen. Nothing but the state of final liberation is to be the ideal for attainment. There should be no desire for wife, husband, children and worldly activity. The aspirant must be encircled by the fence of dispassion on all sides.
Action is for the man of the world, the wisdom is for the sanyasin who has risen above worldliness. Only the man of renunciation with knowledge attains Brahman, and none else. Without perfect renunciation, it is impossible to pursue the path of the knowledge of Brahman.
