Verse 2.3.166

Sanskrit text, Unicode transliteration, Word-for-word and English translation of verse 2.3.166:

सल्-लक्षणं प्रेम-भरस्य कृष्णे कैश्चिद् रसज्ञैर् उत कथ्यते तत् ।
प्रेम्णो भरेणैव निजेष्ट-नाम-सङ्कीर्तनं हि स्फुरति स्फुटार्त्या ॥ १६६ ॥

sal-lakṣaṇaṃ prema-bharasya kṛṣṇe kaiścid rasajñair uta kathyate tat |
premṇo bhareṇaiva nijeṣṭa-nāma-saṅkīrtanaṃ hi sphurati sphuṭārtyā || 166 ||

sat–excellent; lakṣaṇam–characteristic; prema–of love; bharasya–of an abundance; kṛṣṇe–for Śrī Kṛṣṇa; kaiścit–by certain; rasa-jñaiḥ–connoisseurs of essential mellows; uta–certainly; kathyate–is said; tat–for Him; premṇaḥ–of love; bhareṇa–because of the abundance; eva–indeed; nija–own; iṣṭa–worshipable Lord; nāma–of Bhagavān’s names; saṅkīrtanam–congregational chanting; hi–indeed; sphurati–is manifest; sphuṭa–blossomed; ārtyā–anxiousness.

Some knowers of rasa consider nāma-saṅkīrtana alone to be the embodiment and the most excellent symptom of śrī-kṛṣṇa-prema, because, while absorbed in chanting the name of one’s beloved Lord with an anxious, open heart, prema automatically manifests in that nāma-saṅkīrtana.

Commentary: Dig-darśinī-ṭīkā with Bhāvānuvāda

(By Śrīla Sanātana Gosvāmī himself including a deep purport of that commentary)

The Vaikuṇṭha pārṣadas say, “Indeed, those expert in rasa accept nāma-saṅkīrtana to be the very nature, or svarūpa, of pure love of God. According to them, śrī-nāma-saṅkīrtana is the most excellent characteristic of śrī-kṛṣṇa-prema because by singing the name of one’s beloved Lord with the distress of one’s aggrieved heart fully-manifest, one experiences prema. Prema manifests when saṅkīrtana is performed in this way, and also, saṅkīrtana is perfected when it is performed with prema. Therefore, since nāmasaṅkīrtana and prema have a mutual relationship of cause and effect, they are proven to be nondifferent.”
