By filling a vessel, you just pour things into it and don’t really pay much attention to what goes in. Something goes in and it later goes out with no one really caring all that much about it. When you kindle a fire, you tend to it, stir it, make it grow and stay alive. You cause it to rise, to illuminate, to shine.

Now picture a bunch of stick, and something has set fire to them. Do the sticks take an active or passive role? How, if at all, do the sticks and fire interact? How does this image of burning sticks affect you?

Your mind is the bowl / sticks. Information is the water and fire. What kind of knowledge is the water and fire? What kind of person would teach “water knowledge” and what kind “fire knowledge”?

Did that help any?
