CC Antya 6.312
sāvadhāne prabhura kailā ājñāra pālana
The principle of very rigidly carrying out the order of the spiritual master must be observed. The spiritual master gives different orders to different people. For example, Śrī Caitanya Mahāprabhu ordered Jīva Gosvāmī, Rūpa Gosvāmī and Sanātana Gosvāmī to preach, and He ordered Raghunātha dāsa Gosvāmī to strictly follow the rules and regulations of the renounced order. All six Gosvāmīs strictly followed the instructions of Śrī Caitanya Mahāprabhu. This is the principle for progress in devotional service. After receiving an order from the spiritual master, one must strictly try to execute the order. That is the way of success.
