The Upanishads capture the quintessence of Indian spiritual wisdom -- unfolding deepest, highly perceptive reflections on human existence and how it is related to the mysterious cosmos. Authored by enlightened seers over the period of 1500-200 bc., the Upanishadic message is a magnificent vision that raises human consciousness to sublime heights. The Brihadaranyaka Upanishad is one of the ten major Upanishads. A dialectical narration that unabashedly stands up to the rational scrutiny of the modern mind, it is directed towards both the individual aspirant caught up in the dark morass of confusion and the philosophic thinker in search of rare pearls of wisdom from humanity's treasury. Guru Nitya's matchles commentary will enable the reader to discover the ancient seer's timeles insights, to appreciate a fully-developed, integrated system of thought, and, most importantly, to learn to connect with what is real and enduring in his or her own essence. Schematically, the Brihadaranyaka Upanishad -- a brilliant discourse from the Yajur Veda -- is set out in three volumes, entitled: Madhu Kanda, Muni Kanda and Khila Kanda. In his planned three-volume thorough-going, meticulously analytical commentary. Guru Nitya distills the wisdom teaching of the Brihadaranyaka Upanishad, drawing on his intimate understanding of the human psyche, as well as both Eastern and Western philosophy, science, art and literature. Dwelling in turn on each of its 435 mantras, its poetic charm, myths, metaphors, images and symbols, Guru Nitya recreates and expands the Upanishadic vision of our own nature, human interaction, and the cosmos, and their relation to the unmoved essence of all. With highly useful appendices and a comprehensive index, the commentary will hold an enduring appeal for both scholars and discerning readers.
