Vivekachudamani, or The Diamond in the Crown of Discrimination, prose version by Bhagavan Sri Ramana Maharshi

Adi Shankara, i.e., the Original Shankara, unlike the titles of the heads of the monastic orders he founded, or Shankaracharya (788-812 AD) — the greatest philosopher of Hinduism and the founder of the Advaita Vedanta school. His most important works... include commentaries on the Brahma Sutras, 11 major Upanishads, and the Bhagavad Gita. He is also the author of numerous magnificent hymns and religious-philosophical poems, among which is Vivekachudamani (The Diamond in the Crown of Discrimination).
Bhagavan Sri Ramana Maharshi — one of the greatest spiritual Teachers of the 20th century. At the age of 16, he spontaneously attained Enlightenment or Self-realization, the awareness of the true Self. In our time, his teaching serves as an inspiring example of the Path of Knowledge, indicated earlier by the sages of the Upanishads, Buddha (563-483 BC), and Adi Shankara.
At the request of his devotees, Sri Ramana translated the poem Vivekachudamani into Tamil in prose. According to him, Shankara detailed the essence of Vedanta and its meaning in it so that the most earnest among those striving for Liberation could familiarize themselves with it and attain Immortality. Therefore, this edition will be extremely beneficial to all devoted spiritual practitioners.
