The outstanding scientists and philosophers through out the globe acknowledge the inquiries made by our ancient sages in the Upanishads with high reverence. But the students and youth of the present generation in India are not having any introduction in their academic curriculum or in professional fields. The book “Upanishad Ratnavali” is an attempt to provide comprehensive information about 11Upanishads and their contents, in an easily readable style.
