Srimad Bhagavatam Canto 01, Chapter 18, Text 21

SB 1.18.21

athapi yat-pada-nakhavasrstam
jagad viriñcopahrtarhanambhah
sesam punaty anyatamo mukundat
ko nama loke bhagavat-padarthah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
Who can be worthy of the name of the Supreme Lord but the Personality of Godhead, Sri Krsna? Brahmaji collected the water emanating from the nails of His feet in order to award it to Lord Siva as a worshipful welcome. This very water [the Ganges] is purifying the whole universe, including Lord Siva.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
The conception of many gods in the Vedic literatures by the ignorant is completely wrong. The Lord is one without a second, but He expands Himself in many ways, and this is confirmed in the Vedas. Such expansions of the Lord are limitless, but some of them are the living entities. The living entities are not as powerful as the Lord’s plenary expansions, and therefore there are two different types of expansions. Lord Brahma is generally one of the living entities, and Lord Siva is the medium between the Lord and the living entities. In other words, even demigods like Lord Brahma and Lord Siva, who are the chief amongst all demigods, are never equal to or greater than Lord Visnu, the Supreme Personality of Godhead. The goddess of fortune, Laksmi, and all-powerful demigods like Brahma and Siva are engaged in the worship of Visnu or Lord Krsna; therefore who can be more powerful than Mukunda (Lord Krsna) to be factually called the Supreme Personality of Godhead? The goddess of fortune, Laksmiji, Lord Brahma and Lord Siva are not independently powerful; they are powerful as expansions of the Supreme Lord, and all of them are engaged in the transcendental loving service of the Lord, and so also are the living entities. There are four sects of worshipful devotees of the Lord, and the chief amongst them are the Brahma sampradaya, Rudra sampradaya and Sri sampradaya, descending directly from Lord Brahma, Lord Siva and the goddess of fortune, Laksmi, respectively. Besides the above-mentioned three sampradayas, there is the Kumara sampradaya, descending from Sanat-kumara. All of the four original sampradayas are still scrupulously engaged in the transcendental service of the Lord up to date, and they all declare that Lord Krsna, Mukunda, is the Supreme Personality of Godhead, and no other personality is equal to Him or greater than Him.
