"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, mistaking 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."

- Swami Vivekananda, "Hints on Practical Spirituality" (Spiritual Breathing, Dec 29, 1899, Los Angeles Home of Truth), Complete Works: Vol 2
