To practice the regulative principles of bhakti-yoga one should, under the guidance of an expert spiritual master, follow certain principles: one should rise early in the morning, take bath, enter the temple and offer prayers and chant Hare Krsna, then collect flowers to offer to the Deity, cook foodstuffs to offer to the Deity, take prasadam, and so on. There are various rules and regulations which one should follow. And one should constantly hear Bhagavad-gita and Srimad-Bhagavatam from pure devotees. This practice can help anyone to rise to the level of love of God, and then he is sure of his progress into the spiritual kingdom of God. This practice of bhakti-yoga, under the rules and regulations, with the direction of a spiritual master, will surely bring one to the stage of love of God."
