Here the ways of men part: if you wish to strive for peace of soul and pleasure, then believe; if you wish to be a devotee of truth, then inquire.

It is not in how one soul approaches another but in how it withdraws that I know its affinity and solidarity with the other.

All instincts that do not discharge themselves outwardly turn inward - this is what I call the internalization of man: thus it was that man first developed what was later called his soul.

A refined soul is distressed to know that someone owes it thanks; a crude soul, to know that it owes someone thanks.

Your soul will be dead even before your body: fear nothing further.

A soul which knows that it is loved, but does not itself love, betrays its sediment: its dregs come up.
