The Bhagavad- Gita is considered by eastern and western scholars alike to be among the greatest spiritual books the world has ever known. In a very clear and wonderful way the Supreme Lord Krishna describes the science of self-realization and the exact process by which a human being can establish their eternal relationship with God. In terms of pure, spiritual knowledge the Bhagavad- Gita is incomparable. Its intrinsic beauty is that its knowledge applies to all human beings and does not postulate any sectarian ideology or secular view. It is approachable from the sanctified realms of all religions and is glorified as the epitome of all spiritual teachings. This is because proficiency in the Bhagavad- Gita reveals the eternal principles which are fundamental and essential for spiritual life from all perspectives and allows one to perfectly understand the esoteric truths hidden within all religious scriptures. Many great thinkers from our times such as Albert Einstein, Mahatma Gandhi and Albert Schweizer as well as Madhvacharya, Sankara and Ramanuja from bygone ages have all contemplated and deliberated upon its timeless message. The primary purpose of the Bhagavad- Gita is to illuminate for all of humanity the realisation of the true nature of divinity; for the highest spiritual conception.
