Lord Śrī Caitanya Mahāprabhu explained this ātmārāma śloka very vividly before His chief devotee Śrīla Sanātana Gosvāmī. He points out eleven factors in the śloka, namely (1) ātmārāma, (2) munayaḥ, (3) nirgrantha, (4) api, (5) ca, (6) urukrama, (7) kurvanti, (8) ahaitukīm, (9) bhaktim, (10) ittham-bhūta-guṇaḥ and (11) hariḥ. According to the Viśva-prakāśa Sanskrit dictionary, there are seven synonyms for the word ātmārāma, which are as follows: (1) Brahman (the Absolute Truth), (2) body, (3) mind, (4) endeavor, (5) endurance, (6) intelligence and (7) personal habits.
(Srimad Bhagavatam-----1:7:10-----purport).

A student sacrifices his childish proclivities to gain better education. A servant gives up his job for a better job. Similarly, a devotee renounces the material world not for nothing but for something tangible in spiritual value. Śrīla Rūpa Gosvāmī, Sanātana Gosvāmī and Śrīla Raghunātha dāsa Gosvāmī and others gave up their worldly pomp and prosperity for the sake of the service of the Lord. They were big men in the worldly sense. The Gosvāmīs were ministers in the government service of Bengal, and Śrīla Raghunātha dāsa Gosvāmī was the son of a big zamindar of his time. But they left everything to gain something superior to what they previously possessed. The devotees are generally without material prosperity, but they have a very secret treasure-house in the lotus feet of the Lord.
(Srimad Bhagavatam-----1:8:27-----purport).

There is a nice story about Śrīla Sanātana Gosvāmī. He had a touchstone with him, and this stone was left in a pile of refuse. A needy man took it, but later on wondered why the valuable stone was kept in such a neglected place. He therefore asked him for the most valuable thing, and then he was given the holy name of the Lord. Akiñcana means one who has nothing to give materially. A factual devotee, or mahātmā, does not give anything material to anyone because he has already left all material assets. He can, however, deliver the supreme asset, namely the Personality of Godhead, because He is the only property of a factual devotee. The touchstone of Sanātana Gosvāmī, which was thrown in the rubbish, was not the property of the Gosvāmī, otherwise it would not have been kept in such a place. This specific example is given for the neophyte devotees just to convince them that material hankerings and spiritual advancement go ill together. Unless one is able to see everything as spiritual in relation with the Supreme Lord, one must always distinguish between spirit and matter. A spiritual master like Śrīla Sanātana Gosvāmī, although personally able to see everything as spiritual, set this example for us only because we have no such spiritual vision.
(Srimad Bhagavatam-----1:8:27-----purport).

That great souls cheat others may be astonishing to know, but it is a fact that great souls cheat others for a great cause. It is said that Lord Kṛṣṇa also advised Yudhiṣṭhira to tell a lie before Droṇācārya, and it was also for a great cause. The Lord wanted it, and therefore it was a great cause. Satisfaction of the Lord is the criterion of one who is bona fide, and the highest perfection of life is to satisfy the Lord by one's occupational duty. That is the verdict of Gītā and Bhāgavatam.* Dhṛtarāṣṭra and Vidura, followed by Gāndhārī, did not disclose their determination to Sañjaya, although he was constantly with Dhṛtarāṣṭra as his personal assistant. Sañjaya never thought that Dhṛtarāṣṭra could perform any act without consulting him. But Dhṛtarāṣṭra's going away from home was so confidential that it could not be disclosed even to Sañjaya. Sanātana Gosvāmī also cheated the keeper of the prison house while going away to see Śrī Caitanya Mahāprabhu, and similarly Raghunātha dāsa Gosvāmī also cheated his priest and left home for good to satisfy the Lord. To satisfy the Lord, anything is good, for it is in relation with the Absolute Truth. We also had the same opportunity to cheat the family members and leave home to engage in the service of Śrīmad-Bhāgavatam. Such cheating was necessary for a great cause, and there is no loss for any party in such transcendental fraud.
(Srimad Bhagavatam-----1:13:37-----purport).

According to Śrīla Jīva Gosvāmī, a person freed from the three modes of material qualities, namely goodness, passion and ignorance, and situated in transcendence can reach the highest perfection of life without change of body. Śrīla Sanātana Gosvāmī in his Hari-bhakti-vilāsa says that a person, whatever he may be, can attain the perfection of a twice-born brāhmaṇa by undergoing the spiritual disciplinary actions under the guidance of a bona fide spiritual master, exactly as a chemist can turn gun metal into gold by chemical manipulation.
(Srimad Bhagavatam-----1:15:47-48-----purport).

Śrīla Rūpa Gosvāmī and Śrīla Sanātana Gosvāmī were high-ranking ministers of state, but they were able to leave behind them immense writings on transcendental knowledge, while residing only for one night underneath one tree. They did not live even two nights under the same tree, and what to speak of well-furnished rooms with modern amenities. And still they were able to give us most important literatures of self-realization. So-called comforts of life are not actually helpful for progressive civilization; rather, they are detrimental to such progressive life.
(Srimad Bhagavatam-----2:2:4-----purport).

The first duty of a person in the renounced order of life is to contribute some literary work for the benefit of the human being in order to give him realized direction toward self-realization. Amongst the other duties in the renounced order of life of Śrīla Sanātana, Śrīla Rūpa and the other Gosvāmīs of Vṛndāvana, the foremost duty discharged by them was to hold learned discourses amongst themselves at Sevākuñja, Vṛndāvana (the spot where Śrī Rādhā-Dāmodara Temple was established by Śrīla Jīva Gosvāmī and where the actual samādhi tombs of Śrīla Rūpa Gosvāmī and Śrīla Jīva Gosvāmī are laid).
(Srimad Bhagavatam-----2:2:5-----purport).

If one wants to have transcendental pleasure, he must find a person with authority. It is also stated in the Bhāgavatam that simply by hearing from an authoritative source, with the ear and the heart, one can relish the pastimes of the Lord, otherwise it is not possible. Sanātana Gosvāmī, therefore, has especially warned that one should not hear anything about the personality of the Lord from the lips of a nondevotee. Nondevotees are considered to be like serpents; as milk is poisoned by a serpent's touch, so, although the narration of the pastimes of the Lord is as pure as milk, when administered by serpentlike nondevotees it becomes poisonous.
(Srimad Bhagavatam-----3:19:33-----purport).

A man may be very rich materially, but if he is not Kṛṣṇa conscious, he is considered poor. On the other hand, many ācāryas, such as Rūpa Gosvāmī and Sanātana Gosvāmī, used to live beneath trees every night. Superficially it appeared that they were poverty-stricken, but from their writings we can understand that in spiritual life they were the richest personalities.
(Srimad Bhagavatam-----3:29:17-----purport).

Usually, initiation depends on the bona fide spiritual master, who directs the disciple. If he sees that a disciple has become competent and purified by the process of chanting, he offers the sacred thread to the disciple just so that he will be recognized as one-hundred-percent equal with a brāhmaṇa. This is also confirmed in the Hari-bhakti-vilāsa by Śrī Sanātana Gosvāmī: "As a base metal like bell metal can be changed into gold by a chemical process, any person can similarly be changed into a brāhmaṇa by dīkṣā-vidhāna, the initiation process".
(Srimad Bhagavatam-----3:33:6-----purport).
