‘Universal’ means ‘everything, everywhere’ and ‘Osmosis’ means ‘absorbed into it’, so ‘Universal Osmosis’ means,
‘Absorbed into everything, everywhere’.
When everything seems separate, then how can this be so? The answer to this is because we are generally only looking at the surface of it.
We know that all material is made up of a bunch of vibrating atoms with further inner components, holding the bond of material together until the time comes for those bonds to break down. So how can we say that an outer material solid shape of form is its only existing aspect when we know that there’s much more to it than that.
