In other types of yoga processes one does all types of austerity, meditation and penances and finally at the end one gets the samadhi like when we are going through the meal like in Bengal system we eat the bitter first and the sweet is the last like the samadhi- the ecstacy. However Srila Prabhupada said Lord Caitanya is so merciful that He gives us the dessert first like the kids would like to have the apple pie or ice-cream first, then deal with the spinach some other time, if at all. Similarly Lord Caitanya gives us the taste first-the nectar, so that way we already get little taste of bliss then gets us into the main course which is the whole process of bhakti yoga. When we are chanting the holy name by the mercy of the Lord the bliss awakens in our heart.
