I came across this today in my reading … (bolding and emphasis added).
Cc. Adi-lila 2.117
siddhānta baliyā citte nā kara alasa
ihā ha-ite kṛṣṇe lāge sudṛḍha mānasa
siddhānta—conclusion; baliyā—considering; citte—in the mind; nā kara—do not be; alasa—lazy; ihā—this; ha-ite—from; kṛṣṇe—in Lord Kṛṣṇa; lāge—becomes fixed; su-dṛḍha—very firm; mānasa—the mind.
A sincere student should not neglect the discussion of such conclusions, considering them controversial, for such discussions strengthen the mind. Thus one’s mind becomes attached to Śrī Kṛṣṇa.
There are many students who, in spite of reading the Bhagavad-gītā, misunderstand Kṛṣṇa because of imperfect knowledge and conclude Him to be an ordinary historical personality. This one must not do. One should be particularly careful to understand the truth about Kṛṣṇa. If because of laziness one does not come to know Kṛṣṇa conclusively, one will be misguided about the cult of devotion, like those who declare themselves advanced devotees and imitate the transcendental symptoms sometimes observed in liberated souls. Although the use of thoughts and arguments is a most suitable process for inducing an uninitiated person to become a devotee, neophytes in devotional service must always alertly understand Kṛṣṇa through the vision of the revealed scriptures, the bona fide devotees and the spiritual master. Unless one hears about Śrī Kṛṣṇa from such authorities, one cannot make advancement in devotion to Śrī Kṛṣṇa. The revealed scriptures mention nine means of attaining devotional service, of which the first and foremost is hearing from authority. The seed of devotion cannot sprout unless watered by the process of hearing and chanting. One should submissively receive the transcendental messages from spiritually advanced sources and chant the very same messages for one’s own benefit as well as the benefit of one’s audience.
When Brahmā described the situation of pure devotees freed from the culture of empiric philosophy and fruitive actions, he recommended the process of hearing from persons who are on the path of devotion. Following in the footsteps of such liberated souls, who are able to vibrate real transcendental sound, can lead one to the highest stage of devotion, and thus one can become a mahā-bhāgavata. From the teachings of Lord Caitanya Mahāprabhu to Sanātana Gosvāmī (Madhya 22.65) we learn:
śāstra-yuktye sunipuṇa, dṛḍha-śraddhā yāṅra
‘uttama-adhikārī’ sei tāraye saṁsāra
“A person who is expert in understanding the conclusion of the revealed scriptures and who fully surrenders to the cause of the Lord is actually able to deliver others from the clutches of material existence.”
Śrīla Rūpa Gosvāmī, in his Upadeśāmṛta, advises that to make rapid advancement in the cult of devotional service one should be very active and should persevere in executing the duties specified in the revealed scriptures and confirmed by the spiritual master. Accepting the path of liberated souls and the association of pure devotees enriches such activities.
Imitation devotees, who wish to advertise themselves as elevated Vaiṣṇavas and who therefore imitate the previous ācāryas but do not follow them in principle, are condemned in the words of Śrīmad-Bhāgavatam (2.3.24) as stone-hearted. Śrīla Viśvanātha Cakravartī Ṭhākura has commented on their stone-hearted condition as follows:
bahir aśru-pulakayoḥ sator api yad dhṛdayaṁ na vikriyeta tad aśma-sāram iti kaniṣṭhādhikāriṇām eva aśru-pulakādi-mattve ’pi aśma-sāra-hṛdayatayā nindaiṣā
“Those who shed tears by practice but whose hearts have not changed are to be known as stone-hearted devotees of the lowest grade. Their imitation crying, induced by artificial practice, is always condemned.”
The desired change of heart referred to above is visible in the reluctance to do anything not congenial to the devotional way. To create such a change of heart, conclusive discussion about Śrī Kṛṣṇa and His potencies is absolutely necessary. False devotees may think that simply shedding tears will lead one to the transcendental plane, even if one has not had a factual change in heart, but such a practice is useless if there is no transcendental realization. False devotees, lacking the conclusion of transcendental knowledge, think that artificially shedding tears will deliver them. Similarly, other false devotees think that studying books of the previous ācāryas is unadvisable, like studying dry empiric philosophies. But Śrīla Jīva Gosvāmī, following the previous ācāryas, has inculcated the conclusions of the scriptures in the six theses called the Ṣaṭ-sandarbhas. False devotees who have very little knowledge of such conclusions fail to achieve pure devotion for want of zeal in accepting the favorable directions for devotional service given by self-realized devotees. Such false devotees are like impersonalists, who also consider devotional service no better than ordinary fruitive actions.
