Sriman Chaitanya Mahaprabhu displayed the mood of one drowned in the ocean of ecstatic mellows during the course of His last 12 years of manifest pastimes. He wailed day in day out in separation from His beloved Sri Krishna during the Gambhira pastimes at Puri. He appeared fully mad; He laughed deliriously and wept bitterly at other times. He would be lost in sorrow some times and sometimes chant most anxiously as though bitten by the serpent of endless time. In this mood He would visit the Temple of His dear Lord Jagannath and have dialogues with Him; the very same way the Gopis ranted as their Lord of their hearts Sri Krishna united with Him in a different clime at Kurukshetra after a gap of hundred long years. The Gopis were lost in a world of their own as they internally complained and swore at their stone-hearted Lord and so did Sriman Mahaprabhu have the same dealings with Lord Jagannath. Sriman Mahaprabhu had the same mood of the 
Gopis when He was face to face with Lord Jagannath just as the Gopis came face to face with Lord Krishna at Kurukshetra. Lord Mahaprabhu appeared to be the personified mellow of the Gopis as He enacted the final twelve years of His earthly pastimes.
During the Ratha Yatra festival every year Lord Mahaprabhu danced before the Ratha and expressed the mood of the Gopis there. He would say that He has now won the one for whom He had been burning with lusty desires. This was the level of His elevated mood. The separation of Sriman Mahaprabhu from Lord Jagannath was like that of a fire of lust. This lust has no equivalence on the mundane plane. One who is tormented by the separation of the Lord feels this lust unlike the lust of sexual desire. The lust of separation encompasses within itself the joy of union which the Lord felt on meeting Lord Jagannath during the Ratha Yatra festival. Sriman Mahaprabhu was filled with the mood of conjugal love towards Lord Jagannath exactly as Srimati Radharani and desired to take the Lord of His heart back to Vrindavana. This emotion overflowed His entire being and thus He passed His days during the course of the last 12 years of His pastimes. Sriman Mahaprabhu expressed the very same sentiments of Srimati Radharani and expressed Her heartfelt emotions set to melodious poetry. The famous lines of Sriman Mahaprabhu are included in the great works of Sri Rupa Goswami as an anthology of verses in Padyavali. The hankering filled poetry of Sriman Mahaprabhu appeared to be a lusty mundane poetry at the outset but the deep feelings encased in those lines were only read by Sriman Mahaprabhu’s secretary Sri Swarup Damodar. The verse was also overheard by Sri Rupa Goswami who happened to be present at the Ratha Yatra that year and he too understood the deep meaning of the verse rendered by Sriman Mahaprabhu. Sriman Mahaprabhu later discovered the export of the verse as expressed by Sri Rupa Goswami. On knowing this He showered several benedictions on Sri Rupa Goswami and thus transferred onto him the potency of furthering the Bhakti movement by infusing within him the capability of being able to compose numerous transcendental literature of the highest order.
The mood of Sriman Mahaprabhu at the Ratha Yatra festival adorning the mellows of Srimati Radharani is the pinnacle of mood of service to Krishna. One who follows this mood of Srimati Radharani with a view to giving pleasure to the divine couple is said to be in Raganuga. The direct associates of the Lord who have spontaneous attachment to Him are all Ragatmika devotees. Such devotees as headed by Srimati Radharani, Srimati Lalita Devi, Sri Vishakha Devi and all the sakhis. The devotees performing bhajana on the earthly platform, spontaneously seeking shelter under the direct devotees or Ragatmika devotees are said to be Raganuga devotees. The platform of Raganuga sadhana was first set by Sriman Mahaprabhu who directly displayed the feelings of Srimati Radhika. The aspect of such Bhajana was later on enunciated by the like of Sri Swarup Damodar and the six Goswamis of Vrindavana headed by Sri Rupa Goswami.
