This book entitled Atmagatividya is a close sequal to my book on Vedic Concept of Atman which has been recently published. In these two books taken together, I have fairly covered all aspects of Vedic concept of Atman at the Adhidaivika and Adhyatmika levels. However I am well aware that a few important topics like Pranava concept, the Unified Theory of the Vedic seers etc. which I should have dealt with in the former of these two books, have been left out. I shall cover them in my next book on Bhagavad Gita.
