For a person who is suffering in the fire of countless miseries and even for persons who desires to cross the insurmountable ocean of material existence, there is no suitable boat except cultivating the nectar of the narrations of the Supreme Lord's pastimes. The topics of the Lord are the life-sustaining medicine for all types of devotees, and even for those desiring liberation. Even those who desire liberation cannot achieve liberation without these topics. That is described in this verse. Or this is the answer to the question you asked at the beginning “What should a dying person do?” Other than food, there is nothing that can satisfy intolerable hunger. There is no other means of crossing material existence, such as jṣāna. That would be like giving a garland and sandalwood to a person suffering from hunger. This will be explained later. You should not accept jṣāna, by which I cover the great secret of bhakti, as the recommended process. Rasa in this verse means sweetness produced by the topics of the Lord’s pastimes. One should not prescribe any other medicine except this nectar for persons suffering in the great fire of material life.
