Philosophy

“First intention, then enlightenment.” — Buddha

• “Mastering others is strength. Mastering yourself is true power.” — Laozi

• “A man ought to live in this world like a lotus leaf, which grows in water but is never moistened by water.” — Swami Vivekananda

• “Courage is standing up for what you believe in, even when you cannot win.” — Goomoonryong

• “If you think that you will be inferior in doing something, you will be on that road very soon.” — Hagakure

• “Why curse the darkness when you can light a candle? For all the darkness in the world cannot extinguish the light of a single candle!” — St. Francis of Assisi

• “There is something to be learned from a rainstorm. When meeting with a sudden shower, you try not to get wet and run quickly along the road. But doing such things as passing under the eaves of houses, you still get wet. When you are resolved from the beginning, you will not be perplexed, though you still receive the same soaking. This understanding extends to all things.” — Hagakure

• “Iron is full of impurities that weaken it; through forging—by exposure to heat, cold, and hammering—the impurities are forced out and the iron is transformed into razor-sharp steel. Human beings develop in the same fashion.” — Morihei Ueshiba

• “Falling down a flight of one thousand stairs begins with slipping on the first step.” — Confucius

• “Holding onto anger is like grasping a hot coal with the intent of throwing it at someone else; you are the one who gets burned.” — Buddha

• “One often meets his destiny on the road he takes to avoid it.” — Oogway

• “I’m tired of trying to do something worthwhile for the human race, they simply don’t want to change!” — August Dvorak

• “Everything you do in life will be insignificant, but it’s very important that you do it.” — Mahatma Gandhi

• “Do good and happiness will follow; but don’t get caught up in your good deeds. Forget your past and don’t place any hope on the future. Don’t regret the past… because if you do, it will consume you and you’ll find no peace.” — Phra Khru Bah, speaking to orphaned children.

• “You believe a man can change his destiny? — I believe a man does what he can, until his destiny is revealed.” — Katsumoto & Algren

• “He spirals down cold barren space as his safety rope spins silently above him in the everlasting expanse of Mt. Everest” — ???

• “In the Kamigata area, they have a sort of tiered lunchbox they use for a single day when flower viewing. Upon returning, they throw them away, trampling them underfoot. The end is important in all things.” — Hagakure

Notable works

“When you don’t create things, you become defined by your tastes rather than ability. Your tastes only narrow and exclude people. So create.” — Why the Lucky Stiff
