krishna-lila bhagavate kahe vedavyasa,
chaitanya-lilara vyasa — vrindavana dasa’
Vedavyasa has described the pastimes of Krishna in his Bhagavat. The Vyasa of Chaitanya Lila is Vrindavana dasa.’
Sri Narayani devi, the niece of Srivasa Pandita was the mother of Srila Vrindavana dasa Thakura. In his Sri Chaitanya Bhagavata, Vrindavana dasa has described how his mother attained the affection of Sri Chaitanya Mahaprabhu.
"Narayani devi received the entire remnants of Mahaprabhu's meal. Though she was only an insensible child He bestowed His mercy on her in this way."
As a result of this mercy, Srila Vrindavana dasa Thakura, whose life and soul was Sri Gaura-Nityananda took his birth from her womb.
While Sri Narayani devi was still carrying the child in her womb, she lost her husband. After his death she stayed in the house of Sri Vasudeva Datta Thakura, at Mamgachi, where she helped with the housework. Here Vrindavana dasa began his studies.
Srila Vrindavan Das Thakur wrote Sri Chaitanya Bhagavata. First it was called Sri Chaitanya Mangala. In this book he writes about the pastimes of Sri Chaitanya Mahaprabhu and His associates. He has written a lot about the early lila of the Lord.
In the preface to Sri Chaitanya Bhagavata, Sri Bhaktisiddhanta Sarasvati has written, "Narayani devi raised her child in the home of the father of Sri Malini devi where she had accepted shelter."
Vrindavana dasa was born four years after Mahaprabhu took sannyasa. When Mahaprabhu disappeared, Vrindavana dasa was about twenty years old. He was initiated by Sri Nityananda Prabhu. He accompanied Sri Jahnava Mata to the Kheturi maha-mahotsava.
jaya jaya nityananda premamaya dhama
svabhave parama suddha nityananda nama
jagata tarana hetu yanra avatara
ye jana na bhaje sei papera akara
– Shri Nityananda Charitamrita Antya Khanda Chap 13:
“All Glories to Lord Nityananda Prabhu who is supreme abode of the astonishing mellows of pure love for Lord Gauranga Mahaprabhu. Thus by the very nature, the Holy Name of Lord Nityananda is supremely pure and transcendental. Lord Nityananda and His Holy Name have advented to deliver the whole creation. Thus one who does not worship Lord Nityananda through the chanting of His Holy Name is the personified form of all sin.”
"The pastimes of Krishna have been described in the Srimad Bhagavatam by Veda Vyasa. Vrindavana dasa is the Veda Vyasa of the pastimes of Sri Chaitanya. He has composed Chaitanya Mangala which destroys any inauspiciousness for those who hear it. So that we can understand the glories of Chaitanya-Nitai, the essence of the conclusions regarding devotional service as expanded in Srimad Bhagavatam and the limits of the conclusions regarding Krishna bhakti, he has composed this great literature to uplift mankind. To compose such a work is not conceivable for a human being therefore we can understand that Sri Chaitanya Himself is speaking through him. I offer my obeisances tens of millions of times at the lotus feet of that person who has given us such a scripture which can deliver the whole world."
– Chaitanya Charitamrita, extract of Srila Prabhupada’s purport
