The foremost of all the Vaishnavas who reside at Navadwip is Sri Advaita Acarya, whose virtuous presence has made all the worlds blessed. He is the most preeminent preceptor in all fields including knowledge, renunciation and devotion. In explaining Krishna-bhakti he is like unto Lord Shankara (Shiva) himself, and whatever scriptures that exist within the three worlds he explains in the light of Krishna-bhakti.
With the intense eagerness he continually worships the Shalagram of Sri Krishna with Tulasi manjaris and Ganges water. By the momentum of his spiritual force, his loud shouts pierce the coverings of this universe and, resounding throughout Vaikuntha, reach the ears of Sri Krishna. Hearing this loving summons saturated with devotion, Sri Krishna advents Himself.
On the seventh day of the bright fortnight of the month of Magh, the great ocean of ecstasy swelled to its limits, being forcibly attracted by the moon of Advaita, who appeared from the womb of Sri Nabhadevi as the moon appears in the autumn sky. His father, Sri Kuvera, Pandit floated in that ocean of joy. In great happiness gave many gifts in charity to the brahmanas (who voluntarily accept vows of poverty). Very quietly he approached the maternity room to get a glimpse of his newborn son. Then his own face began to shine by the reflected light of that moon-like personage. The residents of Nabagram came running to see the child. Everyone remarked that they had never seen such a beautiful baby. What a pious activity his father must have performed to get such a jewel of a son, and that in his old age. Thus, Ghanasyama sings about this occasion. [B.R.12.1759] The child was named Mangal, and his other name was Kamalaksa.
