Dusk and Night
Venerable Master Hsuan Hua:
Daytime is movement and nighttime is stillness. When stillness reaches an extreme, when the sky grows dark and when that darkness reaches its apex, dawn breaks. When the light of day reaches its apex, night descends. One day and one night are also one movement and one stillness. However, periods of movement and stillness may be long or short.
The Buddha was vigorous in the daytime and throughout the night–constantly vigorous in the six periods of the day and night. He was able to cultivate without resting or slacking off; he applied effort and energetically pushed forward.
Morning and night, in motion and stillness, at all times you can recite. While moving you can recite and change the motion into stillness; when still you can recite and turn the stillness into motion. When there is neither motion nor stillness, your telegram to Amitabha has gotten through and you’ve received his response.
As sun and moon do not stop in space. The sun and moon do not stop in space. Although the sun and moon travel through space, they are not attached to any part of it and do not stop anywhere. They are without attachments.
