In plain words
That is, one must sing one's kīrtana freely, raising one's voice, without pride and possessiveness. What was the mouth given for?
Do you know why you were given a mouth? To bring a morsel of food to the mouth! Do you know why you were given hands? To do silly things? No, to worship God. Do you know why you were given feet? To roam the lanes and alleys! No, no, to walk around the temple of God. Do you know why you were given ears? To listen to the gossip of the town! No, no, to hear the Name of God. Do you know why you were given eyes? Three films a day, two TV programmes, to watch those! No, no, to behold the beautiful form of God.
So we must make these senses holy, make Manas pure, and contemplate God with purity of citta.
The whole Kali age has become an age of impurity
Embodiments of Prema! No one can describe the sweetness and the Ānanda in nāma saṅkīrtana, saying it is like this or like that. The Bhakti and śraddhā with which you remember: in that same measure of Bhakti and śraddhā it bears fruit. It gives Ānanda to match, too. As the flour, so the bread. As the food, so the belch. As much feeling as you bring to your contemplation, so much does that feeling come to fulfilment in you.
