Lord Brahmā was born on a lotus flower grown out of the transcendental abdomen of Garbodaksaya Viṣṇu. Although Lakṣmī was there, He did not require Lakṣmī to give birth to Lord Brahmā. So, Nārāyaṇa or Kṛṣṇa, the Supreme Personality of Godhead, They are omnipotent.
On being approached by Mother Earth that she is overburdened by asuras, Lord Brahmā, along with other demigods, prayed at the shore of Kṣīrodaka ocean, when message came that Kṛṣṇa would appear. Lord Kṛṣṇa says that He comes down to deliver the devotees and annihilate the miscreants.
In this age, the most merciful avatar Śrī Caitanya Mahāprabhu came. Yesterday in the Caitanya Līlā class, we heard how Lord Caitanya was glorying and was giving some sevā to each devotee. Lord Caitanya glorified Guṇarāja Khān of Khulina-grama, who compiled a book named Śrī Kṛṣṇa-vijaya and said that he has completely conquered My heart by describing the glories of Kṛṣṇa because Kṛṣṇa is My life and soul. He was mentioning how all devotees from Khulina-grama are very dear to Him, even the dog of Khulina-grama are dear to Him. Hare Kṛṣṇa!
