In every inquisitive mind the important question of the creation of the phenomenal world arises, and therefore for a personality like Maharaja Pariksit, who was to know all the activities of the Lord from his spiritual master, such an inquiry is not uncommon. For every unknown thing, we have to learn and inquire from a learned personality. The question of creation is also one of such inquiries to be made to the right person. The spiritual master, therefore, must be one who is sama jna, as stated hereinbefore in connection with Sukadeva Gosvami. Thus all inquiries on God which are unknown to the disciple may be made from the qualified spiritual master, and here the practical example is set by Maharaja Pariksit. It was, however, already known to Maharaja Pariksit that everything we see is born out of the energy of the Lord, as we have all learned in the very beginning of Srimad-Bhagavatam (janmady asya yatah [SB 1.1.1]). So Maharaja Pariksit wanted to know the process of creation. The origin of creation was known to him; otherwise he would not have inquired how the Personality of Godhead, by His different energies, creates this phenomenal world. The common man also knows that the creation is made by some creator and is not created automatically. We have no experience in the practical world that a thing is created automatically. Foolish people say that the creative energy is independent and acts automatically, as electrical energy works. But the intelligent man knows that even the electrical energy is generated by an expert engineer in the localized powerhouse, and thus the energy is distributed everywhere under the resident engineer's supervision. The Lord's supervision in connection with creation is mentioned even in the Bhagavad-gita (9.10), and it is clearly said there that material energy is a manifestation of one of many such energies of the Supreme (parasya saktir vividhaiva sruyate [Cc. Madhya 13.65, purport]). An inexperienced boy may be struck with wonder by seeing the impersonal actions of electronics or many other wonderful things conducted by electrical energy, but an experienced man knows that behind the action is a living man who creates such energy. Similarly the so-called scholars and philosophers of the world may, by mental speculation, present so many utopian theories about the impersonal creation of the universe, but an intelligent devotee of the Lord, by studying the Bhagavad-gita, can know that behind the creation is the hand of the Supreme Lord, just as in the generating electrical powerhouse there is the resident engineer. The research scholar finds out the cause and the effect of everything, but research scholars as great as Brahma, Siva, Indra and many other demigods are sometimes bewildered by seeing the wonderful creative energy of the Lord, so what to speak of the tiny mundane scholars dealing in petty things. As there are differences in the living conditions of different planets of the universe, and as one planet is superior to others, the brains of the living entities in those respective planets are also of different categorical values. As stated in the Bhagavad-gita, one can compare the long duration of life of the inhabitants of Brahma's planet, which is inconceivable to the inhabitants of this planet earth, to the categorical value of the brain of Brahmaji, also inconceivable to any great scientist of this planet. And with such high brain power, even Brahmaji has described in his great samhita (Bs. 5.1) as follows:
