From a conversation with a fellow practitioner...
Last night in class we got into my Sambhogakaya theory, which is that when you attain it a loop closes and you awaken in your deity body. It's generally presented that on the 10th Bhumi you generate this Sambhogakaya. But you have the same sense that I do on this with what you said about Garab Dorje. He is already that Sambhogakaya and Dharmakaya Samantabhadra. I would not be surprised if most of us already exist at the Sambhogakaya plane.
Did I tell you about my experience of consciousness transference into a deity?
In one of my OBEs a thangka of Tara appeared in my bedroom and I flew through it. It seems like certain pure lands are actually the dreams or inner landscapes of certain deities. I know by orthodox teachings this is wrong view but I really got the sense of this: Tara is not just an intelligence, but is also an entire dimension. When I appeared in the mind of a deity its mind's eye was like a super information highway of light.
We experience one thought at a time, but this deity was able to process hundreds of thousands of thoughts simultaneously. These thoughts appeared as windows into other realities in which this deity existed. It was somehow nowhere but everywhere. These windows appeared in its mind as a massive swirling vortex.
