We should not for a moment consider even our best-established knowledge of existence as true.
It is awareness only of the colors that our own vision paints on the film of one bubble in one strand of foam on the ocean of being.—Olaf Stapledon (1886 - 1950)
. . .
The world you can perceive is a very small world indeed.
And it is entirely private.
Take it to be a dream and be done with it.
—Sri Nisargadatta Maharaj
