Now came there Raghupati Upádhyáya, a great scholar and Vaishnav of north Bihar (Tirhut). As he bowed, the Master greeted him with "Be thy mind fixed on Krishna,"--to the great delight of the Upádhyáya. At the Master's request he recited verses of his own composition describing Krishna's deeds. [Verses.] The Master had a transport of love as He listened and urged the poet to proceed further. The Upádhyáya marvelled at such fervour, and knew Him to be Krishna himself and not a mortal. The Master asked, "Upádhyáya! what do you consider most excellent?" The poet replied, "Black is the best of colours." "Where is the best abode of the black complexion?" The poet answered, "Mathura is the best of cities." "Which is the best age--boyhood, maturity, or adolescence?" The Upadhyaya replied, "Adolescence is the only age fit for our meditation." "Which do you think is the best among emotions?" "Love is the highest of all emotions (_ras_)." The Master remarked, "Thou hast taught me the true lore", and then in a tremulous voice recited Madhavendra Puri's verses (embodying the above answers). In rapture He embraced the Upádhyáya, who began to dance in a frenzy of love. Vallabh Bhatta marvelled at the sight. With his two sons he fell down at the Master's feet. The villagers flocked thither to see Him, and at His sight became worshippers of Krishna. Vallabh Bhatta stopped the Brahmans who were inviting the Master, saying, "This holy man jumped into mid-Jamuna in ecstasy. I must not detain Him here, but convey Him back to Prayág. Invite Him there, if you list." So saying he carried the Master across in the boat. Avoiding the press of the people, the Master went to the Dashashwamedh ghát and there taught Rup about Krishna's essence, the path of _bhakti_, the lore of emotions, the conclusions of the _Bhágabat_. He imparted to Rup all the doctrines He had learnt from Rámánanda, and infused (His own) force into Rup's heart, in order to make him a perfect doctor of Vaishnav theology. (Verses quoted from the _Chaitanya-chandrodaya_.)
