Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
The lower part of the Lord’s waist is dark and covered with yellow garments and a belt bedecked with golden embroidery work. His symmetrical lotus feet and the calves, thighs and joints of His legs are extraordinarily beautiful. Indeed, the Lord’s entire body appears to be well built.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Lord Siva is one of the twelve great authorities mentioned in Srimad-Bhagavatam (6.3.20). These authorities are Svayambhu, Narada, Sambhu, Kumara, Kapila, Manu, Prahlada, Janaka, Bhisma, Bali, Vaiyasaki, or Sukadeva Gosvami, and Yamaraja. The impersonalists, who generally worship Lord Siva, should learn of the transcendental sac-cid-ananda-vigraha of the Lord. Here Lord Siva kindly describes the details of the Lord’s bodily features. Thus the impersonalists’ argument that the Lord has no form cannot be accepted under any circumstance.
