I hope I have made my point clear. I am a physicist myself but am deeply absorbed in the Vedanta philosophy and its scientific interpretation.
I have written about 20 stanzas by now of what I call  Viswa-upanishad . I will take probably a few years before I finalise every word of it. It will contain all modern scientific knowledge about universe.
I am deeply interested in the propagation of the great teachings and infinite knowledge contained in our Upanishads and Gita. There is no knowledge superior to it and there is no book equal to it. If we put these Upanishads and Gita on one side and all books of the world on the other, the Gita will be still superior.
It is therefore that we should make every effort to spread the message of this vital books to the world and preserve that great cultural heritage which shun signs of invasion and annihilation by the flood of material ideas spreading through the length and breadth of our  country .
Dear Dr. Naik,
Your letter dated 20 March 1960 redirected from my Hd Qrs. (Vrindaban) is duly in hand and I am very much encouraged to go through the contents which are full of valuable informations. The subject matter discussed in my article under reference is authorised as far as it refers to the conclusion of Geeta.
I may also inform you that my concept of anti-matter is exactly what you call it anti-material. Technically it may be that I could not express the exact word used by the physicist but I have tried to explain the word anti-matter in the light and sense of what you say as anti-material which is spirit. But spirit is not अपरा as you have pointed out. In the Bhagwat Geeta The Supreme Truth or the Absolute Personality of Godhead is the transcendental पुरुष and the two energies namely  para  and  apara  are emanations from Him. The  Apara  or the inferior material energy may consist of many other elements
