When I was diagnosed with advanced prostate cancer I was already doing some meditation and I was also reading Vedic scriptures such as the Bhagavad Gita. So I understood in principle that I am not the body, but spirit in essence. This is opposed to what many think, that is, that we ARE our material bodies and we HAVE a spirit. NO!… I AM spirit soul and at this moment I HAVE this material body.
It is explained in the Bhagavad Gita that the Supreme Soul, Krishna, sits in our heart always. He never leaves us.
These 2 simple points of not being the body, and of being accompanied by the Supreme/ God/ Krishna, Yaweh (Jehovah) / The Father, wherever we go, is the basis of all spiritual knowledge.
Thank You and Namaste
