Note 12 — Chapter XXXII · THE SPIRITUAL AND FORMAL WORSHIP OF VISHNU.
Viharilala Mitra translation
The former figure of meditation was that of Virát, the god who with his thousand heads, hands and legs and feet “सहस्रशीर्षः पुरुषं सहस्र बाहु सहस्र पाद्,” shows the Daitya Titan Briareus with his hundred heads and hands; but the figure of worship in this chapter is that of Vishnu, with his four arms, one head and two legs only, as a more compendious form for common and practical worship.
