Prabodhasudhakara (The Nectar-ocean of Enlightenment) is one of the lesser-known works of Sri Sankaracarya, the greatest exponent of monistic Vedanta. It consists of 257 verses divided into 19 sections, which present a lucid exposition of the philosophy of monistic Vedanta and the way leading to the realisation of Ultimate Reality

In the clarity and directness of its treatment of the subject and in the numerous homely analogies that are employed to expound the principles of Vedanta, it is perhaps unequalled even by the other popular works of the great author. But what makes it outstanding is the fact that it completely reconciles knowledge (jnana) and Devotion (bhakti) as equally valid methods for the direct experience of Ultimate Reality. The devotional fervour of the author shines through the last four sections of the work containing some exquisite and unforgettable verses. Further, the author consistently recognises the need for the cessation of the thought-waves of the mind and its absorption into the Source which is pure Being-Consciousness, for the attainment of jnana or Intuitive Knowledge.

This work does not appear to have been translated into English before, though a number of translations in the vernacular are available. The translator has attempted a literal translation, without sacrificing the sense and spirit of the original. This attempt had many constraints because of the profound nature of the subject and the radical differences in idiom between Samskrta and English. It was found necessary to take some liberties with English idiom at places, so that the import and spirit of the original could be faithfully presented. In the opinion of the translator, this would be a better course than compromising with the sense of the original, in order to present an English version which is meticulously idiomatic and possesses literary excellence. We should not forget that we are trying to understand the sublime thoughts of the great author and the philosophy and practice of Vedanta as expounded by him. Notes have been added to many verses to achieve this end. In the translation, implied words and alternative meanings are given within brackets.

The translator hopes that this presentation of this great work of Sri Sankaracarya, will help many spiritual seekers to understand and practise the most essential disciplines for Perfection and Liberation, viz., contemplation on the Self and God-love.
