Dependent origination
There is a discussion about theory and practice, which one is better? Some say theory is better as it produces knowledge, some say practice is better as it produces experience and consequence. For my understanding, I think theory and practice are dependent originated, as theory without practice is useless. For example, we may learn, read and write about swimming, but we never enter the water ourselves. All of our knowledge of swimming is useless; it cannot help us from drowning.
