To take advantage of the methods of atonement, one must be at least somewhat devoted; otherwise there is no chance of ones being purified. It is clear from this verse that even those who take advantage of karma-kanda and jnana-kanda, but are not at least slightly devoted cannot be purified simply by following these other paths. The word prayascittani is plural in number to indicate both karma-kanda and jnana-kanda. Narottama dasa Thakura therefore says, karma-kanda, jnana-kanda, kevala visera bhanda. Thus Narottama dasa Thakura compares the paths of karma-kanda and jnana-kanda to pots of poison. Liquor and poison are in the same category. According to this verse from Srimad-Bhagavatam, a person who has heard a good deal about the path of devotional service, but who is not attached to it, who is not Krsna conscious, is like a pot of liquor. Such a person cannot be purified without at least a slight touch of devotional service.
