Some quotes by Plotinus:

"The stars are like letters that inscribe themselves at every moment in the sky. Everything in the world is full of signs. All events are coordinated. All things depend on each other. Everything breathes together."
"In this state of absorbed contemplation, there is no longer any question of holding an object in view; the vision is such that seeing and seen are one; object and act of vision have become identical."
To a Buddhist, it is an expression of emptiness - Here based on the contemplation of the dependent origination and non-duality teachings. But eventually all such concepts too have to be abandoned. Gate gate paragate parasamgate bodhi svaha.
