When you practice yogic exercises…
When you practice yogic exercise, know that your body is not solidly real— It is appearance-emptiness. Your body is like a dream body.
When you practice yoga exercise, know that sounds are not solidly real— They are sound-emptiness. Sounds are like echoes in the valley.
When you practice yogic exercise, let the mind rest relaxed within itself. All that appears in your mind is naturally liberated.
