The real God is 'The Self'; and only 'The Self' is the real God. It is only Self, which must be invoked.

The supreme knowledge in Srimad Bhagavad Gita is widely regarded as ‘ever new’. Inarguably, it is true that this ancient book is the most imperceptible work in the known literature of human race. The esoteric attribute of Bhagavad Gita however causes a ‘quandary’ upon the modern age people; that they consider Gita as merely of theoretical application in life, and not practical. 

It is indeed the grave need of hour to not only simplify this great message but also to relate the interpretation of mystical verses of Gita with our modern tendencies of life. Such simplification becomes even particularly necessary because our newest age of materialistic wisdom should not be left ‘ever deprived’ of the supreme wisdom of mind, body and soul, which has been bestowed upon the mankind by Bhagavad Gita. 

I pray, this book here, which is nothing but merely a raindrop from the ocean of wisdom of Srimad Bhagavad Gita, strongly appeal your conscience for invoking your Self.
