He is Swami Rangnathanand ji, president Ram krishna mission till, he left for heavenly abode in 2005. He is the person who had  command on the interpretation of Shrimad Bhagwad Geeta, Upnishads, Shrimad Bhaagwad and all other literary books and his exposition of Geeta in the light of modern thoughts and needs transformed us totally and taken ourselves on the path of karmyog  with the excellent efficiency of inside and outside.

My tribute to him if he had not been there. I would never reach to a place where I am today , beginning humbly for the development of humanity.
