Prabhupāda: Utsāhān.
- utsāhān niścayād dhairyāt
- tat-tat-karma-pravartanāt
- sato vṛtteḥ saṅga-tyāgāt
- ṣaḍbhir bhaktiḥ prasidhyati
- (Upadeśāmṛta 3)
Utsāhā is the basic principle, utsāhān and sādhu-saṅga (CC Madhya 22.83), association of sādhu. Simply utsāhān and the association is not sādhu—then it is material. Utsāhā means association of sādhu. Sādhu means devotee. Sādhur eva sa mantavyaḥ (BG 9.30). Who is sādhu? Bhajate mām ananya-bhāk. One who has no other business than to serve Kṛṣṇa, he is sādhu. So the association of such sādhu . . . sādhu, sato vṛtteḥ sādhu-saṅge. Whatever a sādhu does, there is no fault. Everything is right. But still, because we are in this material world, we shall act in such a way that nobody can accuse us. Sato vṛtteḥ. Sādhu is above all this vṛtta, but still, you keep pace with the material world; otherwise your activities will be hampered. Therefore Rūpa Gosvāmī has said sato vṛtti: "The dealings should be very honest." Sato vṛtteḥ sādhu saṅge, ṣaḍbhiḥ, six items. Utsāhān, enthusiasm; dhairyāt, patience. Utsāhān dhairyāt niścayāt, with confidence. So enthusiasm, patience, confidence.
