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.
I am the thread that runs through all these pearls, and each pearl is a religion or even a sect thereof. Such are the different pearls, and God is the thread that runs through all of them; most people, however, are entirely unconscious of it.
-Swami Vivekananda
