Souls never die, but always ...

Souls never die, but always on quitting one abode pass to another. All things change, nothing perishes. The soul passes hither and thither, occupying now this body, now that... As a wax is stamped with certain figures, then melted, then stamped anew with others, yet it is always the same wax. So, the Soul being always the same, yet wears at different times different forms.
 Pythagoras

Quotes from the same author

The animals share with us the privilege of having a soul Alas, what wickedness to swallow flesh into our own flesh, to fatten our greedy bodies by cramming in other bodies, to have one living creature fed by the death of another! In the midst of such wealth as earth, the best of mothers, provides, yet nothing satisfies you, but to behave like the Cyclopes, inflicting sorry wounds with cruel teeth! You cannot appease the hungry cravings of your wicked, gluttonous stomachs except by destroying some other life.
 Pythagoras
Ability and necessity dwell near each other.
 Pythagoras
most men and women, by birth or nature, lack the means to advance in wealth or power, but all have the ability to advance in knowledge.
 Pythagoras
Above the cloud with its shadow is the star with its light. Above all things reverence thyself.
 Pythagoras
Do not go to bed until you have gone over the day three times in your mind. What wrong did I do? What good did I accomplish? What did I forget to do?
 Pythagoras
