Reincarnation
"As in this body, there are for the embodied one childhood, youth, old age, even so is there the taking on of another body." - Bhagavad Gita ['The Lord's Song'] (250 B.C.-A.D. 250)
"All changes, even the most longed for, have their melancholy; for what we leave behind us is a part of ourselves; we must die to one life before we can enter another." - France, Anatole
