te tu taj jagrhu rupam

 tyaktam yat paramesthina

mithuni-bhuya gayantas

 tam evosasi karmabhih

 

Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 

 

The Kimpurusas and Kinnaras took possession of that shadowy form left by Brahma. That is why they and their spouses sing his praises by recounting his exploits at every daybreak.

 

Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 

 

The time early in the morning, one and a half hours before sunrise, is called brahma-muhurta. During this brahma-muhurta, spiritual activities are recommended. Spiritual activities performed early in the morning have a greater effect than in any other part of the day.
