Yogi: I’m not disciplined to sit formally, and I prefer to practice in everyday life whenever I remember to be aware – walking to my car, doing things, and at work.

Sayadaw: It depends on the awareness and quality of mind – if the mind is not stable, then the awareness in daily practice is only superficial. It is not good enough; then, you should do formal sits to settle the mind and grow the awareness.

If you’re skillful in maintaining and sharpening the awareness in daily activities, then formal sits are not necessary.
