The seventh chapter is itself entitled as the yoga of knowledge and experience of the Truth Principle! Mark the excellence of the divine words of the Lord at the commencement of this chapter! The Lord in the first verse asks Arjun to listen. On reading this verse one naturally expects that if the Blessed Lord Himself is asking to listen then it must be something remarkable. This verse speaks of this very divine speciality. The speaker also is not an ordinary one but the teacher of the world the Lord Himself Shri Krishna. For this reason this divine tone is expected as well.

I will relate not just knowledge, as knowledge is just information which can be acquired by mere reading as well. Knowledge along with the way of illuminating I will relate to you and that too (in a complete) manner without any omission. What is creation? Who is the Supreme? Who is the creator of this world? What is the relationship between the creation and the creator? What is this body and what is its governing principle the Self? To know all this is knowledge. It is essential to know this and it is good too to know but just knowing this is not enough. What is the goal of life and how is it to be attained? These queries and then in accordance with it the willingness to progress on the path leading to the attainment of goal.

In the age of science in the scientific language, the theoretical information about principles is knowledge and to experiment it in the laboratory is science!

Supreme is the essence and the substratum of the world. All exist because of Him and He is in all. There is no particle which without Him and there is no moment when He is not there. When this knowledge in the form of wisdom is experienced, then it is natural that along with the experience of abundant peace, joy, the whole secret of this creation by itself is unravelled. In the language of the Upanishad:

'Yasmin vigyate sarva vigyatam bhavati'

On knowing which all is known-that principle the Self and the Supreme Self; this is going to be described by the Gita's Preacher further in this chapter. But prior to this

is a startling revelation:
