The end of life is to be like God, and the soul following God will be like Him.

...[W]hen death comes to a man, the mortal part of him dies, but the immortal part retires at the approach of death and escapes unharmed and indestructible... [I]t is as certain as anything can be... that soul is immortal and imperishable, and that our souls will really exist in the next world.

Envy is the ulcer of the soul

Are you not ashamed of caring so much for the making of money and for fame and prestige, when you neither think nor care about wisdom and truth and the improvement of your soul?

If I tell you that I would be disobeying the god and on that account it is impossible for me to keep quiet, you won't be persuaded by me, taking it that I am ionizing. And if I tell you that it is the greatest good for a human being to have discussions every day about virtue and the other things you hear me talking about, examining myself and others, and that the unexamined life is not livable for a human being, you will be even less persuaded.

False words are not only evil in themselves, but they infect the soul with evil.
