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.
Realize your true nature. That is all there is to do. Know yourself as you are -- infinite spirit. That is practical religion. Everything else is impractical, for everything else will perish.
-Swami Vivekananda
