There are thoughts and feelings within us. Here is a question. Where do they come from? It seems they just happen to us and we don't know their origin. Most of the time, they are triggered by stimuli outside. And that's what's happening to most of us. However, external stimuli are not the origin of thoughts and feelings. They are just triggers. The origin exists somewhere else.

"We live in two worlds, inner world and outer world at the same time", said John Kehoe. In our inner world, there are thoughts and feelings. In our outer world, there are circumstances, environments, and conditions.
