I dont know how I feel about the existence of a subsidiary primary creator deity of each individual universe like brahma is said to be. I'm inclined to reject it out of monotheism while accepting that devas and progenitors (prajapatis, not to be confused with brahma who is also called prajapati or the vedic prajapati) can be creative in a smaller sense, but it does help explain evil in the world if the primary creator was a flawed being subject to maya. its kinda weird how in the hindu trinity (which I take with a grain of salt as a systemized thing also) sustainer/preserver and destroyer/transformer are both regarded as Supreme and timeless in their own right, but not the creator hiranyagharba who has his 100 "years". idk, even if there is a brahma who is firstborn and highest of all created beings (though hes called self-created in a sense in early texts), he is taught to create by the Supreme Lord who is also his soul and whos will presides over his and every other action.
