So it is not a matter of whether it is possible to attain Buddhahood, or if it is possible to make a tile a jewel. But just to work, just to live in … - Shunryu Suzuki

Pleasure is not different from difficulty. Good is not different from bad. Bad is good; good is bad. They are two sides of one coin. So enlightenment should be in practice. That is the right understanding of practice, and the right understanding of our life. So to find pleasure in suffering is the only way to accept the truth of transiency.

Enlightenment is not some good feeling or some particular state of mind. The state of mind that exists when you sit in the right posture is, itself, enlightenment. If you cannot be satisfied with the state of mind you have in zazen, it means your mind is still wandering about. Our body and mind should not be wobbling or wandering about. In this posture there is no need to talk about the right state of mind. You already have it. This is the conclusion of Buddhism.

Bowing helps to eliminate our self-centered ideas... The result is not the point; it is the effort to improve ourselves that is valuable... whether or not it is possible is not the point... Before you determine to do it, you have difficulty, but once you start to do it, you have none.
