Dominant thoughts? or Dominant being?
What you think has little to do with your actions.
The connection between speaking and action needs to be established, good example, when you read the instructions. It is not obvious how to do what the words say, and it is not obvious that understanding can lead you to that action. Seeing an action allows you to copy it: action to action: no translator is needed. But words to action… lots can be lost in the translation.
That is the biggest puzzlement of teachers… and very few are able to create a bridge between words and actions successfully.
So when teachers, wannabe teachers teach that you should change your thoughts, they are screwing with you. They cater to your mind, but only the mind will be happy if you follow the teaching. Not you.
