What is time?

Time and space are understood by various academic disciplines (philosophy, psychology and physics), and which has been understood by meditators for millennia, to be a product of the false self or the ego consciousness.  Time and space is how the false self organizes information, data that is collected and massaged by the physical sense faculties and the thinking mind.  The false self cannot directly know reality because it filters information through the sense faculties and mental conditioning. Time and space does not exist.  Reality is always present, here and now.

This is a complex subject and there are academic books on the subject by such authors as Donald Hoffman and Bernardo Kastrup.
