All arises in emptiness (spaciousness?)
What is emptiness/spaciousness in direct experience without any labels?
Nothing? Insubstantial thought? Maybe more like a rainbow... is a rainbow there? Sure. But there is no substance. And certainly no entity. No person. No 'self''
That sounds great. So it seems like there is a small sense of self that is seen through quite quickly?
Here's one way to explore any remaining sense of self:
So... We have direct experience, which is seeing, hearing, feeling, tasting, smelling + thought.
When there is a sense of self, separate it into the senses that are involved, and inquire into each sense.
For example, let's say I feel a sense of self behind the eyes, and there's a thought 'this is me'. I would inquire:
Sense of self behind the eyes = sensation = are these sensations the self?
Thought 'this is me' = thought = is this thought the self?
Image of self behind the eyes = thought = is this image the self?
Objections will likely rise up. If so, keep inquiring into those, such as 'Of course there is a self, I'm right here'.
Thought 'Of course there is a self, I'm right here' = thought = is that thought the self?
Then maybe there's a feeling/contraction in the chest, so you inquire into that. Are those sensations the self? Where is it?
If you end up in a quiet place, rest there. Remember, no answer is the answer. There is no answer possible from thought. This needs to be felt into and repeated over and over.
