“The order of the spiritual master is the active principle in spiritual life. Anyone who disobeys the order of the spiritual master immediately becomes useless.” (Cc Adi-lila 12:10 Translation)
“Here is the opinion of Śrīla Kṛṣṇadāsa Kavirāja Gosvāmī. Persons who strictly follow the orders of the spiritual master are useful in executing the will of the Supreme, whereas persons who deviate from the strict order of the spiritual master are useless.” (Cc Adi-lila 12:10 Purport)
“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.” (Cc Antya-lila 6.312 Purport)
“The order is received from the Lord, either directly or through the bona fide spiritual master, and to execute that order, however painstaking, is the severe type of penance. One who follows the principle rigidly is sure to achieve success in attaining the Lord’s mercy.” (SB 2.9.24 : Purport)
“Śrīla Viśvanātha Cakravartī Ṭhākura states that one should not care very much whether he is going to be liberated or not, but he should simply execute the direct order received from the spiritual master. If one sticks to the principle of abiding by the order of the spiritual master, he will always remain in a liberated position.” (SB 4.20.13 : Purport)
Srila Prabhupada’s orders are there today for anyone to take up. These orders are the guaranteed method for going back home, back to Godhead.
