The most basic desire-thought is for the 'me' to continue 'tomorrow'. My prestige, my expertise, my achievements, esteem, plans, possessions and struggles, all my empire, it's all put together by thoughts.

The me has no substance. The whole structure of self is but a tangle of memories, empty in the core.

This is not only a theory, there can be a direct perception of the fact, which is called Unitary Perception. UP is simply the factual perception, as opposed to the fragmentary perception of thought, sorrow and fear.
