I have been listening to audiobooks on Buddhism and Hinduism (Dhammapada, Bhagavad Gita, Heart Sutra, Upanishads, Rig Veda, etc.), and am stuck trying to imagine and/or understand how the infinite divine mind (the All, or whatever you want to call it, God, etc..), divides into individual life experiences which have "their own" perceptions and self-experience (atman), and are yet impermanent. And how this relates to the permanent anatman (non-self).
The way my mind imagines it, there is a ball like a balloon filled with tiny points/particles like grains of sand. Each grain of sand is the self-experiencer, but are all part of the whole ball (and yet where this metaphor breaks down is the grains of sand are actually distinct from the ball, but in the All case, they are but tiny aspects of the all or something like that).
In this sense, there is a finite number of grains of sand / selves, and no more and no less can be created. But in the All/anatman case, it seems to subdivide into an infinite number of experiences. So then it's like, afterlife/reincarnation. How does that work? When I die do I get subdivided into several lesser experiences (ranked according to evolution of spiritual development), or merged into a higher single experience composed of many other souls now integrated into one? Or how do more selves get created which have their own perceptions? Why can't we just magically create a self using some physics or biology experiments (which don't involve just having lifeforms reproduce)? Why can't we just "poof" and a new individual experiencer / soul is created out of a test tube of some sort of energy?
All those questions boil down to the fact that I don't understand how the permanent anatman, the divine infinite all/perfection (or if I'm mixing up concepts, let me know), divides into individuals which can have their own conscious awareness (like humans), or at least have their own independent life. There is a "spark" there, where does it come from and how does it perceive itself as independent of the whole? How are more individual selves created? Is there a fixed number of them?
This meme hits home the most, and yet I still don't get how individuals can have their "own" experience (at least from their own perspective), and how the infinite subdivides into these selves.
