On the very day of the Snana, Lord possesses an elephant form in the evening. The story behind this is as follows- Ganpati Bhatt, a most revered worshiper of Brahma, who, after reading all the scriptures, concluded that by taking Darshan of Parma Brahma, a living entity becomes liberated. In the scriptures, he read that Parma Brahma resides in Jagannath Puri. But from somewhere, it was settled in his mind that Parma Brahma possessed a proboscis. So, when he came to Jagannath Puri on Jyeshtha Purnima for Darshan of the Lord and saw that Lord Jagannath did not have a proboscis, then he inferred that he could not be a Parma Brahma.
Ganpati Bhatt further contemplated that if Jagannath had been a Parma Brahma, then how come people who take Darshan of the Lord are coming back? They must be liberated. Thinking about all this, he started going from there. Seeing this, Lord Jagannath felt sorrow, and he took the form of a Brahman and came to him. Lord, and made him understand that Jagannath is the only one whom he has come to meet. In the form of the Lord, Brahman instructed Ganpati Bhatt to go back and see. When he returned, in actuality, Lord Jagannath and Baladeva’s heads were that of the elephant and an elongated proboscis and teeth of the elephant. Then Ganpati Bhatt believed that Jagannath was the only Parma Brahma.
He further acknowledged that Jagannath is the Lord. From then, on the evening of every Snana Yatra, Gaja Vesha is performed. Lord Jagannath and Baladeva are decorated as an elephant, and Subhadra is adorned in the form of a lotus. For Gaudiya Vaishnavas, this is a special occasion because Chaitanya Mahaprabhu, after taking Sannyasa, spent most of his time on the Jagannath Puri.
Chaitanya Mahaprabhu also used to take pleasure in that Snana Yatra. As we discussed above, after Snan, Lord does not give Darshan for 15 days because he resides in a wooden made home called Anabasara, where Shivir caste people serve the Lord. Sri Chaitanya Mahaprabhu himself is Krishna, depicting the mood of Radha Rani. Therefore, his name is also Krishna Virah Vidur. And Jagannath Ji is himself Krishna but depicts the mood of separation from Radha Rani. Therefore, one name of Lord Jagannath is also Radha Virah Vidur. Lord Jagannath chants Radha, and Chaitanya Mahaprabhu chants Krishna. See, how is the transcendental pastime of the Lord?
Then, they both meet in Jagannath Puri. But after the Snana Yatra, when Mahaprabhu fails to take the Darshan of Lord Jagannath, Mahaprabhu cannot bear this separation. Then, being worried and wandering in all directions, Chaitanya Mahaprabhu reaches Alarnath, where a deity of the four-handed Lord Vishnu possesses a conch shell, discus, club, and lotus. And the separation of Chaitanya Mahaprabhu was so extreme that the two hands of Alarnath disappeared, and it became Shyamasundara. And the stone on which Chaitanya Mahaprabhu sat and offered obeisance melted from all four sides, and the stone is also situated as it is today there. Therefore, from then, the devotees of the Gaudiya sect reside only in Alarnath on the Anabasara and perform kirtans and bhajans there.
Conclusion
Therefore, along with the season of festivity, Snana Yatra brings with it a feeling of separation. Thus, it all delineates about the Snana Yatra festival of Lord Jagannath. The day when the Lord Jagannath appeared, and from his wooden Brahma form, mercifully manifested in Jagannath Puri to bestow his mercy upon the living entities of the world. In the temples of ISKCON, this festival of Snana Yatra is also celebrated with great joy and enthusiasm. Therefore, it is a humble request to all the devotees to visit their nearest ISKCON temples, take advantage of this special occasion, and obtain the divine mercy of Lord Jagannath on his appearance day.
