मिथुनीभूय गायन्तस्तमेवोषसि कर्मभि: ॥ ४६ ॥
tyaktaṁ yat parameṣṭhinā
tam evoṣasi karmabhiḥ
te — they (the Kinnaras and Kimpuruṣas); tu — but; tat — that; jagṛhuḥ — took possession of; rūpam — that shadowy form; tyaktam — given up; yat — which; parameṣṭhinā — by Brahmā; mithunī-bhūya — coming together with their spouses; gāyantaḥ — praise in song; tam — him; eva — only; uṣasi — at daybreak; karmabhiḥ — with his exploits.
The Kimpuruṣas and Kinnaras took possession of that shadowy form left by Brahmā. That is why they and their spouses sing his praises by recounting his exploits at every daybreak.
The time early in the morning, one and a half hours before sunrise, is called brāhma-muhūrta. During this brāhma-muhūrta, spiritual activities are recommended. Spiritual activities performed early in the morning have a greater effect than in any other part of the day.
