It's not possible to think nothing, so you think a thought that doesn't expand into something big.

Like focus on breathing... occupy ur mind with it.

Focus on birds chirping around.. Now your mind might wander off to ANGRY BIRDS but pull it back softly. And focus on just sound or sensation.

Idea is to not think about something that expands into an essay. Helpful?

Is there a fundamental difference between this "relaxed" state and some form of exercise involving longer streaks of monotonous movement (say swimming) while focusing on the repetitive motions (and sensations) themselves?

Interesting! I don't think there is much difference. Let's see:

- Both are focusing moments

- Both require full attention to make any sense

- Both call for the best of you.

- Both are delicious (focusing on stuff is the fun of life, innit? )

But one calls for focus naturally (swimming) and the other needs deliberate focus against 'habit of thoughts'.

Hope that answers it.
