Thinking about what meditation is, and practicing meditation are not the same.
The thinking mind cannot simulate its effects.
The thinking mind assumes it is the whole mind. Meditation reveals it to be a tiny subset. Which cannot experience or simulate its superset.
A discussion at the level of this subset is by definition limited.
Among other things, the practice changes the meaning of “I”.
Well there is metacognitive awareness allowing us to think and therefore speak about thinking on a meta level. However the absence of thinking is hard to describe.
