Synopsis ‘Dharma’ is the law of existence codified by the vast ancient Scriptures; the spiritual revelations of the Master Minds; the great Vedic seers, the pious savants, who followed them, and the ancient Acharyas, have explained these Scriptures so as to enable comprehension by common minds. Sanatana Dharma is the ancient Vedic discipline which remains ever fresh and immutable. Civilized world is aware that the great Indian philosophical tradition is contained in the Scriptures known as Upanishads. Upanishads, occurring in the Vedas, record the definitive conclusions of the Vedic seers. These are perceived as the “Veda Sira” – the very content-essence of Vedas. The variety of idiom and phraseology, the didactic exuberance, the amplitude of vision, is mind-boggling, considering their anciency, when the civilization of mankind elsewhere presented a picture of utter barbarity and ignorance. The present work underlines the comprehensive and integrated approach, based on several schools of thought, the foremost being the writing of Bhagwan Shri Ramanujacharya, his monumental work ‘Shri Bhashyam’ in particular. This work catches the spirit of Vedic philosophy. The English exposition is marked by clarity of expression and authoritatively crafted with copious annotations of several ancient works. It would be of immense help for understanding the great message of Vedas by the dedicated reader and is a valuable contribution to the English literature.
