If a person engages in the process of bhakti yoga and yet continues to engage in activities that are detrimental to spiritual progress, his spiritual progress will be very slow. This does not mean that a person must be completely free of all bad habits before he can even begin the process of bhakti yoga. For example, in the Philippines, one teacher saved many young people who were addicted to heroin and other drugs by teaching them the process of bhakti yoga. It took some time before they could completely give up all drugs; but eventually they did.

Sometimes a person is still addicted to cigarette smoking or meat-eating. If he follows the process of bhakti yoga, then gradually he will be able to give up such habits. It is a question of tasting a higher taste. If a person engages in the process of bhakti yoga, he will gradually begin to taste the higher spiritual happiness, and he will be able to give up all vices naturally. After he gives up such bad habits, then his progress will be very rapid.
