The poet, closing this decad: The Lord came with his bed, the serpent, and with the lovely sea of milk, he and the lady of the lotus [Śrī] together, and entered into the dwelling of my body, and there he takes his rest while the many waves of that sea beat about him: Viṭṭucittaṉ praises that Benefactor for the guarding of this town [the self].
