According to Osho, the subtle body’s mind and past conditioning do not change merely because the gross body changes; ordinarily only the body dies and is replaced. Transformation can occur, however, in the catalytic presence of a realized master like Krishna, whose vibration accompanies the subtle body. Love lets one transcend the bodily prison; hatred binds, sometimes necessitating death to break the shell so inner change becomes possible.
Switching bodies is like changing clothes; your habits stay the same unless a wise, loving presence helps you, and love opens the door while hate keeps you stuck.
