Orphic Quotes
Pythagoras and Orphic mysteries stand very high in Greek religion and they have family likeness with Hinduism. Lecky in his History of European Morals quotes an old tradition in Greece that Pythagoras had himself come to India and learnt philosophy from the gymnosophists. It seems he believed in an "all-pervading soul" which is at least one important attribute of Hindu âtman. He believed in rebirth or transmigration; he taught and practised harmlessness or non-injury; chastity was the leading virtue of his school of thought; he taught silence; he taught that the end of man is to "become like God". Orphic mysteries taught release (lysis) from all material entanglements, which is close to moksha of the Hindus.
Ram Swarup
Some say that the body (σῶμα) is the "tomb" (σῆμα) of the soul, their notion being that the soul is buried in the present life; and again, because by its means the soul gives any signs which it gives, it is for this reason also properly called "sign" (σῆμα). But I think it most likely that the Orphic poets gave this name, with the idea that the soul is undergoing punishment for something; they think it has the body as an enclosure to keep it safe, like a prison, and this is, as the name itself denotes, the "safe" (σῶμα) for the soul, until the penalty is paid, and not even a letter needs to be changed.
