SB 3.29.16

Purports 16 continued.

The exact word meaning of the word sattvena is given by Sridhara Svami as dhairyena, or with patience. One shall execute the performance of devotional service with great patience. It is not that because in one attempt or two attempt it is not successful, therefore one should give up the execution of devotional service. One must continue. Srila Rūpa Gosvami says also the same thing, that one should be very much enthusiastic and execute devotional service with patience and with confidence. Patience is required to develop confidence that…, the confidence as "Krsna will certainly accept me because I am engaged in devotional service." And one has to execute according to the rules and regulation, then surely it is going to be successful.
