lol.
don't disparage the enlightened one boys.
I am talking about what is "phenomenon" from the lankavatara sutra, which is also considered to be the seed of zen.
The illusion is real, for a moment. IN 10,000 years, none of us will remain and our cities will be under the ground and returne dto the earth. "as if they were illusion".
They are there now because our minds manifested them, made them physical through our work and will fall away because we will no longer pay them the heed they require to stay standing.
