CC Madhya 3.194
nīlācale yāite mora nāhika śakati
Haridāsa Ṭhākura said, “You are going to Jagannātha Purī, and that is all right, but what will be my destination? I am not able to go to Jagannātha Purī.
Although Śrīla Haridāsa Ṭhākura was born in a Muslim family, he was accepted as a properly initiated brāhmaṇa. As such, he had every right to enter the temple of Jagannātha Purī, but because there were some rules and regulations stipulating that only brāhmaṇas, kṣatriyas, vaiśyas and śūdras (members of the varṇāśrama-dharma system) could enter, Haridāsa Ṭhākura, out of his great humility, did not want to violate these existing rules. He therefore said that he did not have the strength to enter into the temple, and he pointed out that if Lord Śrī Caitanya Mahāprabhu lived within the temple, there would be no way for Haridāsa Ṭhākura to see Him. Later, when Haridāsa Ṭhākura went to Jagannātha Purī, he lived outside the temple, at a place called Siddhabakula. A monastery has now been erected there, known as Siddhabakula Maṭha. People who visit Jagannātha Purī often go to see Siddhabakula and the tomb of Haridāsa Ṭhākura, on the beach by the sea.
