Synopsis The book is titled ‘tadekam’ which is a Sanskrit word, meaning That-One. There are no English equivalents to many important words in the Vedic literature and the authors have deliberately chosen tadekam to most appropriately title for their book.  This book, in a way, is a sequel to the previous book of Vijaykumar Malkalpatte that is titled “Urdhavulam”, again Sanskrit word meaning the tree that has roots above and braches below, the metaphor that appears in Bhagwad-Gita Chapter 15, wherein the author presents the path of self-realization.  The present book tadekam projects before us the nature of Absolute Reality, particularly the nature of mind and the nature of time that is brought together by that ultimate reality.
