Those who just read books cannot understand the teachings and, what’s more, may even go astray. But those who try to observe the things going on in the mind, and always take that which is true in their own minds as their standard, never get muddled. They are able to comprehend suffering, and ultimately will understand all the teachings. Then, they will understand the books they read.
We should not merely expend all our energy collecting pieces of information, but make an effort to experience their validity through insight in our daily life.
