Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
All those personalities had four arms, holding conchshell, disc, mace and lotus flower in Their hands. They wore helmets on Their heads, earrings on Their ears and garlands of forest flowers around Their necks. On the upper portion of the right side of Their chests was the emblem of the goddess of fortune. Furthermore, They wore armlets on Their arms, the Kaustubha gem around Their necks, which were marked with three lines like a conchshell, and bracelets on Their wrists. With bangles on Their ankles, ornaments on Their feet, and sacred belts around Their waists, They all appeared very beautiful.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
All the Visnu forms had four arms, with conchshell and other articles, but these characteristics are also possessed by those who have attained sarupya-mukti in Vaikuntha and who consequently have forms exactly like the form of the Lord. However, these Visnu forms appearing before Lord Brahma also possessed the mark of Srivatsa and the Kaustubha gem, which are special characteristics possessed only by the Supreme Lord Himself. This proves that all these boys and calves were in fact directly expansions of Visnu, the Personality of Godhead, not merely His associates of Vaikuntha. Visnu Himself is included within Krsna. All the opulences of Visnu are already present in Krsna, and consequently for Krsna to demonstrate so many Visnu forms was actually not very astonishing.
The Srivatsa mark is described by the Vaisnava-tosani as being a curl of fine yellow hair on the upper portion of the right side of Lord Visnu’s chest. This mark is not for ordinary devotees. It is a special mark of Visnu or Krsna.
