That is an aspect of what a soul is for sure. The lines you highligted I highlighted as well and responsed with this single line tanka I wrote a couple of years ago and recently rediscovered:

"Everything Everything there is and Everything past All that never came to be and Everything that will last"

In one of my earliest Medium essays, https://medium.com/know-thyself-heal-thyself/eternal-soul-properly-defined-fe7a93e534f8 , I wrote: "Souls are discrete entities; Souls are eternal. Eternal does not imply unchanging. A soul is a sentient being comprised of pure energy of a form and with properties beyond our understanding of energy (“Soul Energy”); it does not dissipate; it does not require a material vessel to encapsulate it; though when incarnate it resides in the brain once formation begins. Soul Energy provides the spark that ignites cell division in the zygote."

I no longer think the soul resides in the brain. I agree with what White Feather wrote here that the soul resides in our energetic biofields that surround our bodies. https://medium.com/grab-a-slice/we-are-broadcasters-35b357da93ad
