You don’t move from intellectual understanding to an actual experience.
In the case of a direct experience of awareness, intellectual understanding is an obstacle. you don’t move from it - you overcome it.
The direct experience of oneness is a direct experience of what is right now, right in this moment, an experience so deep, so complete, that you re aware of this present moment as oneness, as awareness.
When you have an intellectual understanding of what it is you are trying to experience, right now in this moment you are trying to experience what you think oneness is. You are trying to experience your concept. You are not being present with what is.
In order to be present with what is, you need to be present with what is.
In order to be present with what is, you need to stop trying to think about what it is you should be experiencing, what it is you should not be experiencing, what is the right way to experience, what is the wrong way, what is unity, what is not unity, what is oneness, what isn’t.
All those ideas, all this knowledge, all this understanding, you need to let go of all of it.
The more knowledge and understanding you have, the more you need to let go of.
In order to be present with what is, you need to be present with what is. Right now, in this moment, be aware of this moment. That’s all.
