"Practicing the dharma in our day to day lives is in a way similar to exercise. The oral instructions of the gurus, as well as the scriptures of the Buddha, merely provide a general understanding of what true spiritual practice is. The real details are filled in by our actual life experiences, meeting them face to face. It is important to understand the dharma in this way. In my case, I don’t have many opportunities to spend time with my teachers, so it is up to me to practice the dharma as best I can as much as I can. Sometimes there will be things that we really do not understand and need more clarifications about. But the real practice of dharma is relating to our emotions. Practicing in this way is similar to the need to have regular exercise in our lives."
