Pythagors (582 BC ~ 497 BC ) Greek Mathematician

Above the cloud with its shadow is the star with its light. Above all things reverence thyself.

Concern should drive us into action and not into a depression. No man is free who cannot control himself.

Do not eat your heart.

Friends are as companions on a journey, who ought to aid each other to persevere in the road to a happier life.

If there be light, then there is darkness; if cold, heat; if height, depth; if solid, fluid; if hard, soft; if rough, smooth; if calm, tempest; if prosperity, adversity; if life, death.

In this theater of man's life, it is reserved only for God and angels to be lookers-on.

It is better wither to be silent, or to say things of more value than silence. Sooner throw a pearl at hazard than an idle or useless word; and do not say a little in many words, but a great deal in a few.

Rest satisfied with doing well, and leave others to talk of you as they will.

Silence is better than unmeaning words.

Strength of mind rests in sobriety; for this keeps your reason unclouded by passion.

The most momentous thing in human life is the art of winning the soul to good or evil.

The oldest, shortest words - "yes' and "no" - are those which require the most thought.

Virtue is harmony.
