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 less passion there is, the better we work. The calmer we are, the better for us and the more the amount of work we can do. When we let loose our feelings, we waste so much energy, shatter our nerves, disturb our minds, and accomplish very little work.
-Swami Vivekananda
