The Upanishads contain the crux of Vedic knowledge. This ancient wisdom penned by Bhagawan Sri Sathya Sai Baba Himself in Telugu, was first published as a series of articles in the monthly journal, Sanathana Sarathi. They’re verily divine directions for daily living, making us tread the path discovered by the sages of the past, inducing us to revere their vision and their words. ‘Upa’ means the process of studying with Nishta or steadfastness. ‘Shad’ means the attainment of the Ultimate Reality. Each chapter in the book elucidates an Upanishad, culminating in Bhagawan’s exposition of the Brahmanubhava Upanishad. The first Upanishad, Isavasyopanishad is concerned with Gnyana Kanda. Since the opening manthra of this Upanishad starts with the word, ‘Isavasyam’ (permeated by God), the Upanishad is called by that name. Kathopanishad has become famous on account of its clarity and depth of perception. Many of the thoughts expressed in it can be found in the Bhagavad Gita. Mandukyopanishad is the kernel of Vedanta. It is the most profound among all the Upanishads. It is also the chief, having the distinction of being recommended as, by itself, enough to lead man to salvation. The Taittiriyopanishad deals with Brahma Vidya (knowledge of Brahman). It has three sections: Siksha Valli, Ananda Valli, and Bhrigu Valli. The latter two sections are very important for those seeking Brahma Gnyana. These pronouncements on the Upanishads are verily divine capsules to be assimilated by man, to attain the goal of life. Meticulous reading of this book will surely help a sincere aspirant in his Sadhana (spiritual discipline).
