Appearing In Many Species

“The Lord is the all-prevailing Supersoul of all existence, and yet He appears in the form of a boar amongst the animals, in the form of a human being as Rama, Krishna, etc., in the form of a rishi like Narayana, and in the form of an aquatic like a fish. Yet it is said that He is unborn, and He has nothing to do. In the shruti mantra it is said that the Supreme Brahman has nothing to do. No one is equal to or greater than Him. He has manifold energies, and everything is performed by Him perfectly by automatic knowledge, strength and activity.” (Shrila Prabhupada, Shrimad Bhagavatam, 1.8.30 Purport)
