Bhakti yoga assumes that there is a higher power that has created the universe and is all-powerful. This power has the capacity to confer grace and mercy on him and thus protecting him from all the harms and evils. The devotee or bhakta is expected to make himself fit for receiving this divine grace. For this, he has to practice devotion and virtue.
