Superimposition, Authentic Being, and Vasanas

Instead of writing with a thematic strand in mind, I am going to number my observations and questions. I don't have a focus that runs through them, but rather multiple points I want to post about. They are all based on the chapter from Bartley, Advaita-Vedanta.

1. When discussing whether or not agency is innate or superimposed, Samkara states that “were agency an essential feature of identity, it could never be separated from it, just as heat is inseparable from fire” (Brahma-Sutra-Bhasya 2.3.40 / 147). However, contrary to identity and agency, “the supposition that the Brahman has a mode of being that excludes consciousness and another mode that has the form of consciousness that is other than being implies that is internally complex. Being is just consciousness and consciousness is just in being” (Brihadaranyaka Upanisad 2.3.6 / 146). Superimposed qualities depend upon relations with other things for validation and existence, and human beings create these qualities partially based on language. If everything can be encompassed in Brahman and the qualities of Brahman are inexpressible, where is the validity in saying that agency and identity are not one, yet being and consciousness are? By saying that one thing is not essential to the other while another set of things are essentially fused, are we still relying on superimposed qualities (I realize that my language here is a little off, or it seems off, as I am addressing being and consciousness  as things while the first or second page of our reading made the point that neither are considered things and can’t be because both/it are considered absolute meaning-reality (sadba-tattva) My question here, despite my incorrect language, is: how can we understand what is Brahman (in scripture?) and the distinction between essential features if we are still relying on superimposed qualities?)
2. This is a small comment, but since there is no distinction between subject and object, rather a vision of superimposed qualities, the point “that differences are unreal,” what role do imprints, vasanas, play? Are they also superimposed qualities (I thought we talked about these traces as the defining feature that created one’s karmic stream and therefore differences between the reincarnation of people)?
3. “It is illogical to hold that the continuing existence of entities depends on other entities when their natures are constituted by their own specific causes. Interdependence is a human concept and not something that belongs to things as they are in themselves” (164)  Authentic being and its relation to the quote above (Samkara’s) is very interesting to me especially when seen in light of Western philosophy and Christianity. To exist for the sake of others is not an authentic existence to Samkara (as true being/ Brahman does not depend on its relation to other things), yet salvation in the Christian sense and as I understand it has everything to do with death and existence for others (Jesus’ crucifixion, the ultimate sacrifice for others, created salvation and a way out of the trappings of humanity, whether that be sin or mortality).
