In plain words
The poet, of the fruit of this decad: The cowherd who has made his temple in the heart of Viṭṭucittaṉ, born in the clan of the Vēyar; the one coloured like a rich cool cloud; the chief of the cowherds; the king of the immortals [nityasūris]; the nectar of the sages [Sanaka and the rest]: those who can sing of him will themselves always be close to him, like his shadow.
