ŚB 1.8.30

The transcendental pastimes of the Lord are not only bewildering but also apparently contradictory. In other words, they are all inconceivable to the limited thinking power of the human being. 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 Rāma, Kṛṣṇa, etc., in the form of a ṛṣi like Nārāyaṇa, 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 śruti 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. All these statements prove without any question that the Lord’s activities, forms and deeds are all inconceivable to our limited thinking power, and because He is inconceivably powerful, everything is possible in Him. Therefore no one can calculate Him exactly; every action of the Lord is bewildering to the common man. He cannot be understood by the Vedic knowledge, but He can be easily understood by the pure devotees because they are intimately related with Him. The devotees therefore know that although He appears amongst the animals, He is not an animal, nor a man, nor a ṛṣi, nor a fish. He is eternally the Supreme Lord, in all circumstances.
