Yogi: I could be aware of walking, sensations and thinking at the same time. I thought I should only be aware of the walking.

Sayadaw: Don’t focus only on the walking. Because your awareness is sharp, it can pay attention to walking and still know the thoughts.

Your awareness is good, but the problem is that you don’t like the thoughts. 

Yogi: What should I do when I see the thoughts?

Sayadaw: Let the mind know. 

Yogi: Let the mind think?

Sayadaw: No, not let the mind think, but let the mind know that thinking is happening.

You’re not deliberately thinking, right? It just comes; so, you’re not responsible for it. You just intentionally try to be aware – try to notice that thinking is happening.
