CC Madhya 16.64

prati-varṣa nīlācale tumi nā āsibā
gauḍe rahi’ mora icchā saphala karibā
Word for word: 
prati-varṣa — every year; nīlācale — to Jagannātha Purī; tumi — You; āsibā — do not come; gauḍe rahi’ — staying in Bengal; mora icchā — My desire; sa-phala karibā — make successful.
Translation: 
“Do not come to Jagannātha Purī every year, but stay in Bengal and fulfill My desire.”
Purport: 

The mission of Śrī Caitanya Mahāprabhu is to spread the only medicine effective in this fallen Age of Kali — the chanting of the Hare Kṛṣṇa mahā-mantra. Following the orders of His mother, Śrī Caitanya Mahāprabhu was residing at Jagannātha Purī, and the devotees were coming to see Him. However, the Lord felt that this message must be spread very elaborately in Bengal, and in His absence there was not a second person capable of doing it. Consequently the Lord requested Nityānanda Prabhu to stay there and broadcast the message of Kṛṣṇa consciousness. The Lord also entrusted a similar preaching responsibility to Rūpa Gosvāmī and Sanātana Gosvāmī. Nityānanda Prabhu was requested not to come every year to Jagannātha Purī, although seeing Lord Jagannātha greatly benefits everyone. Does this mean that the Lord was refusing Nityānanda Prabhu a fortunate opportunity? No. One who is a faithful servant of Śrī Caitanya Mahāprabhu must execute His order, even if one has to sacrifice going to Jagannātha Purī to see Lord Jagannātha there. In other words, it is a greater fortune to carry out Śrī Caitanya Mahāprabhu’s order than to satisfy one’s senses by seeing Lord Jagannātha.

Preaching Caitanya Mahāprabhu’s cult throughout the world is more important than staying in Vṛndāvana or Jagannātha Purī for one’s own personal satisfaction. Spreading Kṛṣṇa consciousness is Śrī Caitanya Mahāprabhu’s mission; therefore His sincere devotees must carry out His desire.

pṛthivīte āche yata nagarādi grāma
sarvatra pracāra haibe mora nāma

The devotees of Lord Caitanya must preach Kṛṣṇa consciousness in every village and town in the world. That will satisfy the Lord. It is not that one should act whimsically for his own personal satisfaction. This order comes down through the paramparā system, and the spiritual master presents these orders to the disciple so that he can spread the message of Śrī Caitanya Mahāprabhu. It is the duty of every disciple to carry out the order of the bona fide spiritual master and spread Lord Caitanya’s message all over the world.
