Time is an artifact of your physical senses

"Time, therefore, is an artifact of your physical senses. Disconnect yourself from your physical senses, and time no longer has meaning. There is no way to measure time without access to your physical senses. Even if you count numbers in your mind, all you have is the current count, your present-moment memories of the “past,” and your present-moment projection of the “future.” Both past and future are present-moment projections, but they are not real in the sense of having a position in space-time."
