So I have heard in unreliable regions of the internet...
Often when the Buddha spoke it was in hints, in something that still needed some interpretation.
Often when the Buddha spoke it was with a specific listener in mind, the answer given was there to make sense to that person.
Often when the Buddha spoke he was creating a specific effect, he was giving a teaching which did not immediately extend to a general lesson.
I thought it was interesting to discuss these, because it does make a difference as to how you approach reading the sutra’s. Often it is tempting to just take a sutra and say, I am the questioner and let the Buddha speak to you, but you are forgetting that he is pitching his answer at a very different kind of person.
