SB 9.9.7
dharayisyati te vegam
rudras tv atma saririnam
yasminn otam idam protam
visvam sativa tantusu
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Like a cloth woven of threads extending for its length and breadth, this entire universe, in all its latitude and longitude, is situated under different potencies of the Supreme Personality of Godhead. Lord Siva is the incarnation of the Lord, and thus he represents the Supersoul in the embodied soul. He can sustain your forceful waves on his head.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The water of the Ganges is supposed to rest on the head of Lord Siva. Lord Siva is an incarnation of the Supreme Personality of Godhead, who sustains the entire universe by different potencies. Lord Siva is described in the Brahma-samhita (5.45):
ksiram yatha dadhi vikara-visesa-yogat
sañjayate na hi tatah prthag asti hetoh
yah sambhutam api tatha samupaiti karyad
govindam adi-purusam tam aham bhajami
“Milk changes into yogurt when mixed with a yogurt culture, but actually yogurt is constitutionally nothing but milk. Similarly, Govinda, the Supreme Personality of Godhead, assumes the form of Lord Siva for the special purpose of material transactions. I offer my obeisances at Lord Govinda’s lotus feet.” Lord Siva is the Supreme Personality of Godhead in the same sense that yogurt is also milk although at the same time it is not milk. For the maintenance of the material world there are three incarnations — Brahma, Visnu and Mahesvara (Lord Siva). Lord Siva is Visnu in an incarnation for the mode of ignorance. The material world exists predominantly in the mode of ignorance. Therefore Lord Siva is compared here to the longitude and latitude of the entire universe, which resembles a cloth woven of threads extending for both its length and breadth.
