Due to envy, many asuras describe Krsna to be like a black crow or an incarnation of a hair. Sri Caitanya Mahaprabhu told Sanatana Gosvami how to counteract all these asuric explanations of Krsna. The word kaka means crow, and kesa means hair. The asuras describe Krsna as an incarnation of a crow, an incarnation of a sudra (a blackish tribe) and an incarnation of a hair, not knowing that the word kesa means ka-isa and that ka means Lord Brahma and isa means Lord. Thus Krsna is the Lord of Lord Brahma.
Some of Lord Krsna's pastimes are mentioned in the Mahabharata as mausala-lila. These include the stories of the destruction of the Yadu dynasty, Krsna's disappearance, His being pierced by a hunter's arrow, the story of Krsna's being an incarnation of a piece of hair (kesa-avatara) as well as mahisi-harana, the kidnapping of Krsna's queens. Actually these are not factual but are related for the bewilderment of the asuras who want to prove that Krsna is an ordinary human being. They are false in the sense that these pastimes are not eternal, nor are they transcendental or spiritual. There are many people who are by nature averse to the supremacy of the Supreme Personality of Godhead, Visnu. Such people are called asuras. They have mistaken ideas about Krsna. As stated in Bhagavad-gita, the asuras are given a chance to forget Krsna more and more, birth after birth. Thus they make their appearance in a family of asuras and continue this process, being kept in bewilderment about Krsna. Asuras in the dress of sannyasis even explain Bhagavad-gita and Srimad-Bhagavatam in different ways according to their own imaginations. Thus they continue to remain asuras birth after birth.
As far as the kesa-avatara (incarnation of hair) is concerned, it is mentioned in Srimad-Bhagavatam (2.7.26). The Visnu Purana also states: ujjaharatmanah kesau sita-krsnau maha-bala.
Similarly, in the Mahabharata:
