Prabhupāda: Yes, gosvāmī or svāmī, the same meaning. One who has been able to control his senses... Generally, everyone is controlled by the senses. When one becomes controller of the senses, then he's gosvāmī. So generally, we give this designation to the sannyāsīs because sannyāsa means who has fully control of the senses. One should not accept sannyāsa whimsically. One must know about himself, how far he can control the senses. Therefore, generally, sannyāsa is not accepted until one is sixty years old. But in this age there is no guarantee whether we are going to live up to sixty years old age. So sometimes younger generation also offered sannyāsa. Because Caitanya Mahāprabhu accepted at the age of twenty-four years. We are not, of course, imitating Caitanya Mahāprabhu. But for executing Caitanya Mahāprabhu's mission, if we are sincerely working for Him, then we can take sannyāsa at an early age. Then... But when one is actually a sannyāsa, a sannyāsī, master of the senses, he can be addressed as gosvāmī or svāmī. Yes?
Pradyumna: "The gosvāmīs do not deliver lectures of the Bhāgavatam capriciously. Rather, they execute their services most carefully, following their predecessors, who delivered the spiritual message unbroken to them. Those who listen to the Bhāgavatam may put questions to the speaker in order to elicit the clear meaning, but this should not be done in a challenging spirit. One must submit questions with a great regard for the speaker and the subject matter. This is also the way recommended in the Bhagavad-gītā. One must learn the transcendental subject by submissive aural reception from the right sources. Therefore these sages addressed the speaker Sūta Gosvāmī with great respect."
