Strongly recommend studying the Reconstructionist Tradition for all comrades—Jewish and otherwise—pursuing spiritualism and materialism/non-dualism together.

My Rabbi shared this brief philosophical outline of Reconstructionist Prayer which has helped me develop my framework. Reconstructionism seeks to strip back Jewish Spirituality to a nucleus which is compatible with the Materialist conception of the modern world while still keeping a vibrant spiritual life and concept of divinity.
To me, God is an abstraction for talking about the universe entire. It is a call to grounding humility. From that perspective, the typical prayer-call for intercession does not work. This paper outlines an approach of tapping into divine love and divine consciousness for the strength to take agency rather than a request for intercession.
It keeps the profound contemplative outlet of prayer without needing an omniscient and personified God figure.
