Reality implies constancy. Constancy is composed of change, one of the few
things in reality that is constant is change. Change implies movement from
where we were to where we will be after we get on with it. Movement always
involves some degree of friction, and the more you move, or the longer you
move, the more friction you are discussing here. Friction brings heat and a
lot of friction brings us a lot of heat. The only place that movement
doesn't bring friction is in outer space. Now it also happens that heat
does not generate light, and so you can have hot feelings, deep feelings,
true and sincere convictions, and not have one iota of rationality or
reality involved, after you have been through change and movement and, yes,
friction.
