We often hear “Look at that” in reference to something beautiful, awful or interesting. We never hear “Look at nothing,” e.g., at the space between two objects in a room or between two thoughts. When we do that, you will notice, the mind stops.
The fastest way to stop thinking is to notice nothing. Silence, for example. Or the space between this word and the next. Do this frequently. The mind is thing-addicted. No-thing slaps it silly.
If I think of myself mostly as a body, I will see the world primarily in material terms.
We don’t actually die. What happens is, we serve the common good; we create a space for others. Ancestor worship, while pleasing to our ancestors, is a bit misplaced.
