Bhakti has two meanings Bhajjate bhakti and Bhajanam bhakti. Bhajjate bhakti means Sadhana bhakti that's the bhakti you have to do and Bhajanam bhakti means once you do Sadhana bhakti and purify your heart and you receive Divine bhakti, well that's the Bhajanam bhakti then you get that Divine power, his Divine love.
So we have to do bhakti then with God's grace, with the grace of a Saint, we will receive Divine bhakti and that bhakti lasts forever. That's his Divine power, receiving which, we gain entrance to his Divine abode and his Divine leelas.
So this bhakti is very important to understand. So far I broke it down in two categories: Sadhana bhakti and Prema bhakti. Sadhana bhakti you do Prema bhakti receive. Now let's understand it in more detail. It is actually broken down into three Sadhana bhakti, Bhav bhakti and Prema bhakti.
