Just as treasures are uncovered from the earth, so virtue appears from good deeds, and wisdom appears from a pure and peaceful mind. To walk safely through the maze of human life, one needs the light of wisdom and the guidance of virtue.

Unnatural deeds do breed unnatural troubles.

People's good deeds we write in water. The evil deeds are etched in brass.

I have no patience for anybody who doubts me, none at all.

The barrier to success is not something which exists in the real world; it is composed purely and simply of doubts about ability.

The only limit to our realization of tomorrow will be our doubts of today.
