He is a disciple of Madhavendra Puri, and constitutes one of the figures amongst the Pancatattva. In an earlier incarnation he was Lord Siva. He was born in a varendra brahmana family on the seventh day of the bright fortnight in the month of Magha, 1355 Saka (1433 AD), in the village named Lauda in Srihatta.
According to Bangabhasa O Sahitya, Advaita Prabhu was born in 1434 AD and met Vidyapati in 1458 AD. Advaita's former name was Kamalaksa (Kamalakanta) Vedapancanana. His two wives were Sita Devi and Sri Devi. His son Acyutananda was born of Sita Devi (1425 Saka 1503 AD), followed by Krsnadasa, Gopala, Balarama, Svarupa, and Jagadisa Misra. While Sri Devi gave birth to one son named Syamadasa (Premavilasa 24).
From Lauda, Advaita Prabhu moved to the village of Navahatta and later to Santipura. He also had a house at Navadvipa. In 1480 Saka (1558 AD), at the age of 125 years (i.e. 25 years after the disappearance of Lord Caitanya) Advaita Prabhu passed away. (Advaita Vilasa)
However, according to Premavilasa 24, Advaita Prabhu was born in Santipura. He studied the Vedas and other scriptures under a scholar named Santacarya in Phullavati village near Santipura, where he was awarded the title Acarya. The genealogy of Advaita Prabhu can be found in Premavilasa 24. Also books such as Valyalilasutra (in Sanskrit), and Advaitavilasa, Advaitamangala, Advaita Prakasa, Sitacarita (in Bengali) present detailed information on Advaita Prabhu.
To verify the meeting of Advaita with Vidyapati, it is known that in 1330 Saka (1408 AD) Vidyapati received the endowment of Bisaphi village from Sivasimha. Vidyapati was born around 1307 Saka (1385 AD), and was a contemporary of Candidasa. Vidyapati mentions their meeting one another in songs he composed in 1325 Saka (1403 AD).
One manuscript of the Bhagavata which was copied by Vidyapati is still available and carries the date of copying as 1379 Saka (1457 AD). Evidence shows that Vidyapati was alive until 1401 Saka (1479 AD). In 1485 AD Advaita Prabhu, at the age of fifty two, arrived at the room where Lord Gauranga was born. Much earlier he undertook a pilgrimage. Hence his meeting with Vidyapati should be taken as a fact.
The foremost of all the Vaisnavas who reside at Navadvipa is Sri Advaita Acarya, whose virtuous presence has made all the worlds blessed. He is the most prominent preceptor in all fields including knowledge, renunciation and devotion. In explaining Krsna-bhakti he is like unto Lord Sankara himself, and whatever scriptures that exist within the three worlds he explains in the light of Krsna-bhakti.
With the intense eagerness he continually worships Sri Krsna 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 Krsna. Hearing this loving summons saturated with devotion, Sri Krsna advents Himself.

"All glories to Advaita Prabhu, the incarnation of the Supreme Personality of Godhead. He induced Krsna to descend and thus delivered the entire world." [CC Antya 8.4]
"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 he 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 Navagram came running to see the child. Everyone remarked that they had never seen such a beautiful baby. What a pious activities his father must have been performed to get such a jewel of a son, and that in his old age? Thus Ghanasyama sings about this occasion." [Bhaktiratnakara 12.1759] The child was named Mongal and his other name was Kamalaksa.
Advaita Acarya is the combined incarnation of Mahavisnu and Sadasiva (who resides in Goloka). His two consorts, Sita and Sri are manifestations of Yoga Maya. Once when Advaita performed worship, whatever gods and demigods He used to meditate upon He saw all gathered at Lord Caitanya's lotus feet, offering prayers. Raising up his two hands, Advaita exclaimed in great ecstasy, "Today all the days of my life have produced a successful result, as all my desires have been fulfilled. My birth and activities have finally born fruit. I have directly perceived Your two lotus feet, which are proclaimed throughout the four Vedas but are unattainable thereby. Now, by Your causeless mercy, You have revealed Yourself to Me."
Mahaprabhu replied, "Acarya, now you should perform My worship." First Advaita Acarya washed the Lord's two lotus feet with water scented by flower petals and then with water scented with sandalwood. Then He placed on His lotus feet Tulasi manjari dipped in sandalwood paste along with arghya - an auspicious offering of rice, durva grass, yogurt etc. His eyes brimming with tears, he offered incense, ghee lamps, flowers, sandalwood paste, and some foodstuffs. After offering various prayers he loudly proclaimed the Lord's glories with auspicious shouts. "All glories to the Lord and maintainer of the universe, the Lord of all that lives. All glories to Gauracandra, the ocean of mercy. All glories to the most munificent incarnation of Sri Krsna Caitanya Mahaprabhu, whose form is all-enchanting. All glories to He who is decorated with the ornaments of Srivatsa and Kaustubha. All glories to He who has revealed the Hare Krsna Maha-mantra. All glories to He who enjoys the pastimes of accepting devotion unto Himself. All glories to Mahaprabhu who reclines on the bed of Ananta Sesa. All glories to the refuge of all living entities. [CBh. Madhya 6.116]
Hearing Advaita's prayer's Mahaprabhu replied, "My dear Acarya, I am very pleased by your prayers. Now you can ask from me any benediction you like."
Then Advaita requested that, "My only request is that you distribute love of Krsna even to women, laborers and the ignorant fools as well. [CBh. Madhya 6.167]
A Nrsimha-sila and Deities, fashioned after a picture of Sri Sri Madan-Gopal that were worshiped by Advaita Acarya are still residing at Santipur in Madan-Gopal Para. Santipur is a short distance from Krsnanagara.
The place on the banks of the Ganga where Advaita Acarya worshiped salagram and called out to the Lord to please descend to the world is known today as Babla. A temple has been built in memory of Advaita Acarya's pastimes there.
