That's a very helpful clarification regarding terminology.  I actually thought that article was too complicated but shared the link to show the source of the poem.  Objectification as described in the article is a very good way too understand the stream of thinking which keeps us in the cyle of rebirth.

That said, I would like to present the the following in reference to the coreSelf being a power source.  A power source is not exactly a typical self or being. But it surely gives life to the selves which come in varied forms like humans, gods, animals, ghosts, and so on.

Consider this:  If the coreSelf cuts off the power and disables it from powering the 5 senses and the mind, then there is containment of the so-called power source.  That is when the coreSelf has a chance of experiencing itself.

What is that like? Can one describe the experience? Without powering up and animating the mind, the sense of identity, the body and psyche, the whole samsaric display of a being/ psyche vanishes.

Would sparks still fly out of the power source which is fully  "self" contained?

This is worthy of investigation!
