Dear KRS Sir,Srimathi Dr. Renuka Ji,
Bhagawan is not talking about a body and mind that is deceased. He is talking about suicide, where a ‘healthy’ mind decides to end the life of a body.
I came across an interesting point of view in the Upanishad.
Atma Hatya means false identifications of Atma with body. That is the real suicide from sciptural view.
Here is but one reference. Do not know the authenticity of the source.
THE VEDAS, UPANISHADS, AND PURANAS(c. 1500-c. 500 B.C.)RigvedaChandogya UpanishadIsha UpanishadBrahma PuranaPadma PuranaSkanda PuranaJabala Upanishad
Maharishi's entire discussion must be taken into account what point he is making. Since the body is not yours, ego cannot cause deliberate harm to the body. That is what he means.
Eating bad food and lack of discipline are incidental harm done and should not be confused with ego's need to deprive the body of life.
Again like you say I am no expert but want to make common sense meaning out of what is said by Maharishi
