Difficulties mastered are opportunities won
Keep your face to the sun and you will never see the shadows
Happiness is when what you think, what you say, and what you do are in harmony
Where there is ruin, there is hope for a treasure
Resist much, obey little
The scientific observer of Nature is a kind of mystic seeker in the act of prayer
