Goddess Aset and the child Heru (Preceptor and aspirant)
I think this statement of yours put things very succinctly:
“Surrender in the sense of giving up one’s unrighteous ways (egoism) for wisdom and truth.”
The surrender to the divine is a relinquishing of ego, so an aspirant is giving up something that is illusory in favor of something that is true and real from a higher perspective.
The focus on Divinity is to be understood as a focus on truth. An advanced teacher, having discovered divinity has also “as if become divine” yet the direction of reverence is not towards the ego personality of the teacher albeit purified through the teachings, but rather the reverence is due to the divinity that has been discovered by the teacher and which to the extent is operating dynamically in that personality.
