Bhakti
In bhakti, we depend on Krishna’s strength, not our own.
Purification
Just meditating on Gaura lila in the mind will purify us so much, because there is no question of committing offences.
Showing Our Determination
Practical action is the best way to show our determination. So while chanting, we should show our determination to be attentive. This attracts Krishna's attention.
Pure Devotion
Pure devotion means that one is very eager and enthusiastic to serve the Lord at all time without any laziness.
