Dighanakha asked the Buddha, “Gautama, what is your teaching? What are your doctrines? For my part, I dislike all doctrines and theories. I don’t subscribe to any at all.“
The Buddha smiled and asked, “Do you subscribe to your doctrine of not following and doctrines? Do you believe in your doctrine of not-believing?“
Somewhat taken aback, Dighanakha replied, “Gautama whether I believe of don’t believe is no importance.”
The Buddha spoke gently, “Once a person is caught by belief in a doctrine, he loses all his freedom. When one becomes dogmatic, he believes his doctrine is the only truth and that all other doctrines are heresy. Disputes and conflicts all arise from narrow views. They can extend endlessly, wasting precious time and sometimes even leading to war. Attachment to views is the greatest impediment to the spiritual path. Bound to narrow views, one becomes so entangled that it is no longer possible to let the door of truth open.“
…Dighanakha asked, “But what of your own teaching? If someone follows your teaching will he become caught in narrow views?”
“My teaching is not a doctrine or a philosophy. It is not the result of discursive thought or mental conjecture like various philosophies which contend that the fundamental essence of the universe is fire, water, earth, wind, or spirit, or that the universe is either finite or infinite, temporal, or eternal. Mental conjecture and discursive thought about truth are like ants crawling around the rim of the bowl — they never get anywhere. The things I say come from my own experience. You can confirm them all by your own experience…My goal is not to explain the universe, but to help guide others to have a direct experience of reality. Words cannot describe reality. Only direct experience enables us to see the true face of reality.”
“I must state clearly that my teaching is method to experience reality and not reality itself, just as a finger pointing at the moon is not the moon itself. An intelligent person makes use of the finger to see the moon.“
