Your memories are eroding away. The futures you anticipate, will mostly not come to pass, and the real richness is in the moment. And it's not necessarily some kind of 'Be Here Now' feel-good thing because it doesn't always feel good. But it always feels. It is a domain of feeling. It's primary.
Memory training is great psychedelic training.
Cultivate an ongoing stream of self-description, telling yourself what is happening. Get used to the idea that mind can penetrate the immediate surface of being and reveal the tactile density of it as a manifold whose measure cannot be immediately taken by the eyes, that it's deep, it's connected, it's complex. Everything holds within itself the anticipation and the memory of everything else.
Think about this for a moment, we grow so inured to these religious forms, think about the notion of instituting at the center of your religion a rite where you eat your god is probably a memory of a relationship to some kind of a psychedelic experience of some sort.
Our self discoveries make us each a microcosm of the larger pattern of history. The inertia of introspection leads toward recollection, for only through memory is the past recaptured and understood. In the fact of experiencing and making the present, we are all actors.
