Nārada Muni did not mention Kṛṣṇa's killing Vyomāsura, which means that he was killed on the same day as the Keśī demon. The Keśī demon was killed in the early morning, and after that the boys went to tend the cows on Govardhana Hill, and it was there that Vyomāsura was killed. Both demons were killed in the morning. Akrūra was requested by Kaṁsa to arrive in Vṛndāvana by evening. After receiving instruction from Kaṁsa, Akrūra started the next morning via chariot for Vṛndāvana. Because Akrūra himself was a great devotee of the Lord, while going to Vṛndāvana he began to praise to the Lord. Devotees are always absorbed in thoughts of Kṛṣṇa, and Akrūra was constantly thinking of Lord Kṛṣṇa's lotus eyes.
