From Self-Development and the Way to Power, by L. W. Rogers (8)

The degree to which mind can control circumstances and dominate matter
is far greater than is generally believed. Our impressions about
matter are very illusory. No form of matter is permanent. Change goes
on everywhere at every instant, by physical laws in the physical body
and by astral and mental laws in our invisible bodies. We are not the
same being, physically, mentally or spiritually, any two days in
succession. The very soul itself is subject to this law of change. It
may expand and shine out through the physical organism resplendent, or
it may only faintly glimmer through a constantly coarsening body.
