(Kadamba Kanana Swami, 27 February 2013, Vrndavan, India, Caitanya Caritamrta Seminar 2)
It is described that Madhavendra Puri was the śaktyāveśa-avatāra of Sri Caitanya Mahaprabhu. That explains everything; that explains where Madhavendra Puri got that extraordinary quality of Krsna consciousness from; he got it from Caitanya Mahaprabhu afterall. Saktyāveśa-avatāra, is described as the jiva, a living being, who becomes divinely empowered by the Supreme Personality of Godhead. And not only empowered with pure devotional service, any pure devotee is empowered, but śaktyāveśa-avatāra is more empowered than the pure devotee.
It is said that the śaktyāveśa-avatāra is not only empowered with pure devotion but he is also empowered with a special ability to perform a great mission. So in this way, Madhavendra Puri performed this extraordinary mission of first of all establishing this unalloyed pure devotional service to Krsna and we remember that at the end of his life he was served by two disciples, one was Isvara Puri, the other was Ramachandra Puri. Isvara Puri served him very nicely and Ramachandra Puri was very critical.
It is said,
ayi dīna-dayārdra nātha he
dayita bhrāmyati kiṁ karomy aham, (Caitanya Caritamtra Madhya-Lila 4.197)
Oh my Lord, oh my merciful master, oh master of Mathura, when shall I see you again because if I’m not seeing you my agitated heart has become unsteady. Oh, most beloved one what shall I do now?
This was the mood of Madhavendra Puri at the end of his life. The mood of separation from Krsna.
