represents  bhakti , and Kāmsa symbolically represents material fear. When a pure devotee always fears material association, his real position of  bhakti  is manifested, and he naturally becomes uninterested in material enjoyment. When the six sons of Marīci are killed by such fear and one is freed from material contamination, within the womb of  bhakti  the Supreme Personality of Godhead appears.
