All activities begin with the creation of the total energy, the mahat-tattva. Then, by the agitation of the three guṇas, the physical elements are created, as well as the mind, ego and the controllers of the senses. All of these are created one after another by the inconceivable energy of the Lord. In modern electronics, a mechanic may, by pushing only one button, set off an electronic chain reaction, by which so many actions are carried out one after another.
