Mind, Higher Mind, Ego, Self etc.
We need words and concepts to help understanding, but understanding is only on the surface.
Because what we are seeking on our 'Inner Journey' is not on the surface, more questions come, more words, more thinking.
Ultimately we have to drop all mind stuff.
Only in 'sensing-experiencing' what is beneath the surface, then letting all go, even what we find in the 'emptiness', can we make real discoveries.
By surrendering wholly and unreservedly to not knowing, we may magically come to know!
