Try reading the following paper while keeping the Mind Only Buddhist interpretation of our world in mind.
In 2005, an essay was published in Nature asserting that the universe is mental and that we must abandon our tendency to conceptualize observations as things. Since then, experiments have confi rmed that — as predicted by quantum mechanics — reality is contextual, which contradicts at least intuitive formulations of realism and corroborates the hypothesis of a mental universe. Yet, to give this hypothesis a coherent rendering, one must explain how a mental universe can — at least in principle — accommodate (a) our experience of ourselves as distinct individual minds sharing a world beyond the control of our volition; and (b) the empirical fact that this world is contextual despite being seemingly shared. By combining a modern formulation of the ontology of idealism with the relational interpretation of quantum mechanics, the present paper attempts to provide a viable explanatory framework for both points. In the process of doing so, the paper also addresses key philosophical qualms of the relational interpretation. (Making Sense of the Mental Universe)
Edit: The explanation offered in the linked paper, without saying as much, provides a very reasonable way to see Buddhist rebirth occurring without there being any soul or pudgala being reborn. Nothing need fly out of the body or transmigrate anywhere.
Instead, the classic Buddhist description of karma alone giving rise to a new life works perfectly. Rather than conceive of ourselves as fundamentally material beings, we can conceive of our personal individuality as being (a part of a “mental universe”) enclosed within a Markov blanket.
If there is still karma, a new Markov blanket or bodily form will be “reborn” or rearise after the extinction of its prior existence. In Kastrup’s way of putting it, our physical bodies are themselves Markov blankets causing or allowing us to arise as forms separate from the wholeness of the mental universe.
I suppose we might venture to say that enlightenment occurs when the karma, or reason for our separation in a Markov blanket, is gone and “we” remain the whole (of the mental universe) without being reborn (in a body).
