Śrīla Bhakti Siddhānta Saraswatī Ṭhākur’s commentary on the third verse of Śrī Upadeśāmṛta.
The following is a translation of Śrīla Bhakti Siddhānta Saraswatī Ṭhākur’s poetic Bengali translation, Bhāṣā, and Bengali prose commentary, Anuvṛtti, on Śrīla Rūpa Goswāmī Prabhu’s Śrī Upadeśāmṛta.
These texts were published in Śrī Gauḍīya Darśan, in Volume 2, Issue 11, 10 June 1957, Volume 2, Issue 12, 12 July 1957, and Volume 3, Issue 1, 12 August 1957. In combination with Śrīla Bhakti Vinod Ṭhākur’s Pīyūṣa-varṣiṇī-vṛtti, they were also published as a book from Śrī Chaitanya Sāraswat Maṭh by Śrīla Bhakti Sundar Govinda Dev-Goswāmī Mahārāj in 1970.
“The Upadeśāmṛta of Śrīla Rūpa Goswāmī is also extremely good for us.”
—Śrīla Bhakti Sundar Govinda Dev-Goswāmī Mahārāj,

Remaining indifferent to all practices, principles, and topics of interest that exist related to the pursuits of jñān, karma, and anyābhilāṣ, and engaging exclusively in the practice of devotion is utsāha.
yā niśā sarva-bhūtānāṁ tasyāṁ jāgarti saṁyamī
yasyāṁ jāgrati bhūtāni sā niśā paśyato muneḥ
(Śrīmad Bhagavad-gītā: 2.69)
[“Those who have full self-control are awake in that which is night for all beings, and all beings are awake in that which is night for the sages who see.”]
“Devotion to the Lord is the soul’s one and only aim of life.” This is niśchaya. “Conviction in the three paths of jñān, karma, or anyābhilāṣ cannot produce any good; the soul should follow the path of devotion exclusively.” Such firm conception is niśchaya.
“The three paths of jñān, karma, or anyābhilāṣ make the soul fickle. The path of devotion is the only steady path for the pure soul.” Such firm faith is dhairya. “The path of devotion will never cause anyone harm.” Such conception is dhairya.
ye ’nye ’ravindākṣa vimukta-māninas
tvayy asta-bhāvād aviśuddha-buddhayaḥ
āruhya kṛchchhreṇa paraṁ padaṁ tataḥ
patanty adho ’nādṛta-yuṣmad-aṅghrayaḥ
tathā na te mādhava tāvakāḥ kvachid
bhraśyanti mārgāt tvayi baddha-sauhṛdāḥ
(Śrīmad Bhāgavatam: 10.2.32–3)
[“O lotus-eyed Lord, those who consider themselves liberated but are devoid of devotion to You have impure intelligence. They ascend to the supreme abode with great difficulty but then fall down from there because they have no regard for Your feet. Your devotees, however, O Lord, who are bound by affection for You, never fall from the path.”]
khaṇḍa khaṇḍa hai’ deha yāya yadi prāṇa
tabu āmi vadane nā chhāḍi hari-nāma
(Śrī Chaitanya-Bhāgavat: Ādi-khaṇḍa, 16.94)
[“Even if this body is cut into pieces and I breathe my last, I will never stop chanting the Lord’s Name.”]
Understanding that all the duties prescribed for jñānīs and karmīs are distinct from service to Kṛṣṇa, remaining indifferent to them, and engaging in the practices of devotion is tat-tat-karma-pravartana. Performing the activities that are appropriate for one’s own stage within the three stages of devotees and not making a show of performing the activities meant for a stage different from the one in which one is situated is tat-tat-karma-pravartana.
Understanding that jñānīs, karmīs, and anyābhilāṣīs are all materialistic fools and avoiding their association is saṅga-tyāga. Only the association of devotees is desirable. Jñānīs and other nondevotees do not honour those who associate with devotees. So, let all one’s efforts to obtain honour from karmīs and jñānīs be gone. One should not maintain any connection with such persons whatsoever.
In jñānīs, the conditioned ego is predominant, and in their endeavour to overcome their conditioning, they engage in transitory practices. The thirst of karmīs is similarly only temporary, and there is no need to even mention the anyābhilāṣīs in this regard. We should avoid these three types of transitory egotists and follow the conduct of the devoted sādhus who always take shelter in the Name. The pursuits of karma, jñān, and anyābhilāṣ are never steps on the path of devotion.
jñāna-vairāgyādi bhaktira kabhu nahe aṅga
(Śrī Chaitanya-charitāmṛta: Madhya-līlā, 22.141)
[“Knowledge and renunciation are never limbs of devotion.”]
These three paths, separate from devotion, are unreal, that is, non-eternal.
yasyāsti bhaktir bhagavaty akiñchanā
sarvair guṇais tatra samāsate surāḥ
harāv abhaktasya kuto mahad-guṇā
manorathenāsati dhāvato bahiḥ
(Śrīmad Bhāgavatam: 5.18.12)
[“All the gods and all virtues reside in the bodies of those who have unconditional devotion to the Lord. Where are the virtues of non-devotees, riding the chariot of the mind, who always wander in search of external ends”]
Thus, only the practice of devotion is sādhu-vṛtti, and following the sādhus is the path of devotion.
Enthusiasm for Kṛṣṇa’s service, conviction in Kṛṣṇa’s service, steadiness in Kṛṣṇa’s service, engaging in activities for the purpose of Kṛṣṇa’s service, avoiding the association of nondevotees of Kṛṣṇa, and following the devotees of Kṛṣṇa—devotion develops by engaging in these six practices.
