“ After hearing the bird's prayer, I inquired, "Who are you, and where are you coming from? You look like a swan, and your bodily color is that of a crow." That bird said, "Please understand that I am the swan-carrier of Lord Brahma. The reason for my body having attained a black color I will relate to you.
Just close to Saurashtra (Surat) there is one beautiful lake, from where this wonderful heavenly lotus came from. ”

“ You are the protector of the devotees, who have control over their senses. And you are the foremost of all the devotees of the Supreme Lord Krishna. Great souls such as Brihaspati are always chanting your glories. ”

“ My two arms became two lotuses and my two legs became two lotuses, and the rest of my body became the fifth lotus. From Durvasa Muni's eyes fire started to emanate: "O sinful one, you will stay in that form for one hundred years." After cursing me, he immediately disappeared. Fortunately, I was able to remember the Tenth Chapter of Ṥrīmad Bhagavad-gītā. And today, I have become free from the curse. Due to your crossing over me, you fell to the ground and your body became black. ”
