In the Vedic dictionary it is said, "The Supreme Lord is performing inconceivably wonderful pastimes, displaying His energy. His person is full of different potent energies, and His determination is itself actual fact. In this way the Personality of Godhead is to be understood." We may think to do something, but there are so many impediments, and sometimes it is not possible to do as we like. But when Krsna wants to do something, simply by His willing, everything is performed so perfectly that one cannot imagine how it is being done. The Lord explains this fact: although He is the maintainer and sustainer of all material manifestation, He does not touch this material manifestation. Simply by His supreme will everything is created, everything is sustained, everything is maintained, and everything is annihilated. There is no difference between His mind and Himself (as there is a difference between ourselves and our present material mind) because He is absolute spirit. Simultaneously the Lord is present in everything; yet the common man cannot understand how He is also present personally. He is different from this material manifestation, yet everything is resting on Him. This is explained here as yogam aisvaram, the mystic power of the Supreme Personality of Godhead.
