This is where the original concept of godforms comes from. If you read material from the likes of Israel Regardie, Aleister Crowley, and the Golden Dawn, they use the word to refer to any small-g gods that are not The One True God ™ aka the Eternal Source.
Meaning that the gods from other pantheons were seen as aspects of the capital-G God, in much the same way as angels are.
For example, the Assumption of Godforms is a technique where you choose a god from whatever pantheon (The Golden Dawn and Thelema use mostly Greek and Egyptian deities) and take on its character traits by invoking it through word and gesture.
A modern version of the Assumption of Godforms could possibly be the technique of standing in what is referred to as Wonder Woman Pose (though no one would ever refer to it as an Assumption of Godforms. It’s used in psychology!) where you stand with legs hip width apart and hands on the hips, like the heroine is often depicted as standing, in order to to take on the traits of confidence and self assuredness.
NOTE: The way the term “godform” is used by people on this forum, referring to a deity that one is an aspect of, is not the most widely known, or accepted, definition. In fact, it doesn’t seem to be used in the same way by anyone outside of this small group,
