Why would any thoughts be occurring? They are just thoughts. Some are helpful and some are not. By helpful, I mean the kinds of thoughts that are spiritual in nature, that take us beyond our confusion. Unhelpful thoughts are just plain or confusing thoughts.
Good and bad are thoughts you are having about thoughts. Having a random thought about murdering someone doesn’t mean you have any desire to, or that there is something wrong with you. You are not your thoughts. Ever.
But if you are focused on good thoughts and identify with good thoughts, then bad thoughts will scare you. You will think that there is both good and bad in you. Then you get all that westernized philosophical nonsense about metaphoric demons and angels inside us.
When you were a child, you were taught to use words and think in order to hold together a certain view of being alive in the world. “Think before you speak” and all that jazz. We resist silence because it threatens to destroy our world and we are stuck in compulsive thoughts because that is how we have been taught to create and preserve our world.
However, the nuance here is that the absence or presence of words have nothing to do with it. The only thing that matters is that you remember yourself as the space in which words/images come and go. You are neither the words nor the images. You are just the awareness into which they manifest and dissipate.
