Don't engage your heart in grief over the past or you wont be ready for what is coming.

Do not hate what you do not know, for the greater part of knowledge consists of what you do not know.

When proven wrong, the wise man will correct himself and the ignorant will keep arguing.

Vanity prevents improvement

Do for this life as if you live forever, do for the afterlife as if you will die tomorrow.

How strange and foolish is man. He looses his health in gaining wealth. Then to regain health he wastes his wealth. He ruins is present while worrying about his future - but weeps in the future by recalling his past. He lives as though death shall never come to him - but dies in a way as if he were never born.

Of all the follies the greatest is to love the world.
