Kāma-rūpā means that bhakti which is typified (rūpyate) or impelled by conjugal feelings (kāma), a particular type of thirst. Sambandha-rūpā means that bhakti undertaken or impelled by thirst caused by relationship. Though kāma-rūpa-bhakti is a type of relationship, it is labeled separately, since it is the chief relationship. It is similar to saying, “Everyone is coming, and the king is also coming.” Though the word, “everyone,” includes the king, special mention is made of the king because of his importance.
