Cultivate silence and stillness.

You have your best thoughts in silence, solitude, and meditation. When you relax and think deeply, you are giving your inmost powers the best opportunity to reveal themselves. Constant action and expression uses up your mental capital. To continue growing and materializing useful ideas, you must have frequent times of mental relaxation, concentration, and silence.

Beware the modern tendency to hurry and waste. The time you give to quiet and intelligent meditation will repay you well. Cultivate quietness, poise, and deliberateness. It is at times of inward stillness that you can best hear the voice of God and learn His will. It is then that you most clearly realize the Divine presence and power.
