If you want to be a Yogi, you must be free, and place yourself in circumstances where you are alone and free from all anxiety. He who desires a comfortable and nice life and at the same time wants to realise the Self is like the fool who, wanting to cross the river, caught hold of a crocodile, mista...king it for a log of wood (Vivekachudâmani, 84.). "Seek ye first the kingdom of God, and everything shall be added unto you." This is the one great duty, this is renunciation. Live for an ideal, and leave no place in the mind for anything else. Let us put forth all our energies to acquire that, which never fails — our spiritual perfection. If we have true yearning for realisation, we must struggle, and through struggle growth will come. We shall make mistakes, but they may be angels unawares.
