This kind of pursuit is something I am interested in, and I’m glad to see you pursue it.
One thing you could look for, if you want, is the “psychological constitution” being written by a text. People are psychological beings and the ideas they hold or try to practice shape their overall psychological makeup, affecting how they feel about things and act. So, in the Bhagavad-Gita, we are told that it is good to be detached from the fruits of action, but to act anyway. What effect would that idea have if EAs took it (to the extent that they haven’t already)? Or a whole population? (Similarly with its advice to meditate.) EAs psychologically relate with the fruits of their action, in some way, already. The theistic religions can blend relationship with ideals or truth itself with relationship with a person. What difference would that blending make to EAs or the population at large? I would guess it would produce a different kind of knowing—maybe not changing object-level beliefs (although it could), but changing the psychology of believing (holding an ideal as a relationship to a person or a loyalty to a person rather than an impersonal law, for instance).
