The Personality of Godhead, being full of all conceivable and inconceivable potencies, is the absolute Supreme Whole. Impersonal Brahman is a partial manifestation of the Absolute Truth realized in the absence of such complete potencies. The first syllable of the word bhagavān is bha, which means “sustainer” and “protector.” The next letter, ga, means “leader,” “pusher” and “creator.” Va means “dwelling” (all living beings dwell in the Supreme Lord, and the Supreme Lord dwells within the heart of every living being). Combining all these concepts, the word bhagavān carries the import of inconceivable potency in knowledge, energy, strength, opulence, power and influence, devoid of all varieties of inferiority. Without such inconceivable potencies, one cannot fully sustain or protect. Our modern civilization is sustained by scientific arrangements devised by many great scientific brains. We can just imagine, therefore, the gigantic brain whose arrangements sustain the gravity of the unlimited number of planets and satellites and who creates the unlimited space in which they float. If one considers the intelligence needed to orbit man-made satellites, one cannot be fooled into thinking that there is not a gigantic intelligence responsible for the arrangements of the various planetary systems. There is no reason to believe that all the gigantic planets float in space without the superior arrangement of a superior intelligence. This subject is clearly dealt with in the Bhagavad-gītā (15.13) where the Personality of Godhead says, “I enter into each planet, and by My energy they stay in orbit.” Were the planets not held in the grip of the Personality of Godhead, they would all scatter like dust in the air. Modern scientists can only impractically explain this inconceivable strength of the Personality of Godhead.
