The basic teaching of Buddhism is the teaching of transiency or change. That everything changes is the basic truth for each existence. No one can deny this truth and all teaching of Buddhism is condensed within it. This is the teaching for all of us. Wherever we go this teaching is true. This teaching is also understood as the teaching of selflessness. Because each existence is in constant change, there is no abiding self.
There is no man in the world free from trouble or anguish, though he were King or Pope.
If there is a meaning in life at all, then there must be a meaning in suffering. Suffering is an ineradicable part of life, even as fate and death.
Be a lamp unto yourself, be a refuge to yourself. Take yourself to no external refuge. Hold fast to the Truth as a lamp; hold fast to the Truth as a refuge.
All beings tremble before violence. All fear death. All love life. See yourself in others. Then whom can you hurt? What harm can you do?
Just as a bird, wherever it goes, flies with its wings as its only burden, so too, the bhikkhu becomes content with robes to protect his body and with almsfood to maintain his stomach, and wherever he goes he sets out taking only these with him. Possessing this aggregate of noble virtue, he experiences within himself a bliss that is blameless.
