Mind has been crammed, by psychologists and materialists, into the brain.
We are told mind is an epiphenomenon of brain activity, although no coherent theory of consciousness and inner experience yet exists to back up this contention. In contrast, a spiritual perspective, in common with the great teachers of the past, teaches that the mind is without limit, stretching to the very borders of Eternity.
When you think of something real, be it a place, an event, a distant star or a person alive or dead, your mind touches what it thinks about. Mind travels faster than light, knowing no material boundaries.
We assume that current science enables us to know so much more than the ancients, but those who could use their minds without limit may have penetrated reality to a much greater extent than we imagine.
