“A two-headed man should have twice the IQ, and the ability to have internal dialogues externally.”

“What you are, and who you are should provide greater clarity about where you have been and where you are headed. Although one distinguishes spiritual from physical nature, the ultimate unification of the two is the consequence of the struggle for internal, external and eternal – peace.”

“There are two big forces at work, external and internal. We have very little control over external forces such as tornadoes, earthquakes, floods, disasters, illness and pain. What really matters is the internal force. How do I respond to those disasters? Over that I have complete control.”

“A man's actions are determined by necessity, external and internal.”

“Few people think more than two or three times a year; I have made an international reputation for myself by thinking once or twice a week.”
