“This one question -- "What do I know for certain?"-- is tremendously powerful. When you look deeply into this question, it actually destroys your world. It destroys your whole sense of self, and it's meant to. You come to see that everything you think you know about yourself, everything you think you know about the world, is based on assumptions, beliefs, and opinions-- things you believe because you were taught or told that they were true. Until we start to see these false perceptions for what they really are, consciousness will be imprisoned within the dream state.”
I’ve been thinking about this, and it seems to be true. Everything we are told by parents, teachers, preachers contains a vast amount of untruth, and in a way it contaminates the mind with suppositions, imaginations, and assumptions. You can throw it all away and start again from just mature experience of the world and better tools, clarity and reason to see more deeply into our experience.
In a way, losing your belief in what other people tell you is very healthy. It leads to a healthy scepticism, a resistance to letting arbitrary others shape your inner world. That by itself is not enough to stop dreaming, but it’s a good first step, you still need to become sober and stop imagining things.
But I like the quote above also for pointing out that the self is also made up of suppositions.
