say music into literature? in Buddha psychology is there a theory about channeling one object into another? projection perhaps?
One as two, two as one. Projecting one image into another is a very rudimentary form. The deeper, more subtle levels of these exercises, I imagine, would be realizing the unity between objects. Manifesting from unmanifest, the void. It's more of an awareness than an actual play of visuals and ideas. When you see that you and the tree are not separated. I guess, though, that you should start from visuals. I do some basic visual work to help tease this awareness, like meditating on me and a tree, the wind, elements, and then seeing myself as the the element, looking at 'me'. Such as a leaf tumbling from a tree onto my head. I imagine myself as the leaf, not me. Or the suns rays pouring down on me. I imagine third person, both the light and my body, my being. Then I see myself as the light, pouring into me. I suppose it is an exercise in expanding awareness. It is difficult to explain what happens when that part of you is suddenly awakened, if only for a moment, and you truly do see yourself transpersonally.
