Shankara's Vivekachudamani is a popular Vedanta text which gives its basic principles. This translation, a work by a disciple of Sri Ramakrishna, was transcribed from notes taken by Ida Ansell, an American devotee who attended Swami Turiyananda's classes at the turn of the century. Text in Sanskrit, transliteration, and English translation. A verse index in Sanskrit is included.
The disciple must have great power of endurance. Life seems comfortable; and you find the mind behaves well when everything is going well with you. But if something goes wrong, your mind loses its balance. That is not good. Bear all evil and misery without one murmur of hurt, without one thought of unhappiness, resistance, remedy, or retaliation. That is true endurance; and that you must acquire.
-Swami Vivekananda
