The Supreme Personality of Godhead controls the material activities manifested by the three modes of material nature. As stated in Bhagavad-gita, nirgunam guna-bhoktr ca: the Supreme Personality of Godhead is always transcendental to the material qualities (sattva-guna, rajo-guna and tamo-guna), but nonetheless He is their controller. The Lord manifests Himself in three featuresas Brahma, Visnu and Mahesvarato control these three qualities. He personally takes charge of sattva-guna as Lord Visnu, and He entrusts the charge of rajo-guna and tamo-guna to Lord Brahma and Lord Siva. Ultimately, however, He is the controller of all three gunas. Lord Brahma, expressing his appreciation, said that because Lord Visnu had now taken charge of the activities of goodness, there was every hope that the demigods would be successful in fulfilling their desires. The demigods were harassed by the demons, who were infested with tamo-guna. However, as Lord Brahma has previously described, since the time of sattva-guna had now arrived, the demigods could naturally expect to fulfill their desires. The demigods are supposedly well advanced in knowledge, yet they could not understand the knowledge of the Supreme Personality of Godhead. Therefore the Lord is addressed here as anantaya. Although Lord Brahma knows past, present and future, he is unable to understand the unlimited knowledge of the Supreme Personality of Godhead.
