Hibou seems to say, consider this.
Matter can seem quite logically one, when large enough it can be noticed by senses.
Things very naturally come to mind as the mind frequently notices.
Mind is matter, matter seems a constantly changing one.
Earth is well over 99% made up of nonliving matter, a small part of 1% of the living forms are animals which are way down the list in prominence with plants leading the pack along with a few others noticeable life forms. Where life forms appear senses will be present. It may seem to some human minds that one is all, so with that in mind the mind can seem to one a small matter.
