The Supreme Personality of Godhead, Krsna, says in Bhagavad-gita that the natural laws being enacted are correct in all activities because of His superintendence. No one should think that nature is working automatically, without superintendence. The Vedic literature says that the clouds are controlled by the demigod Indra, heat is distributed by the sun-god, the soothing moonlight is distributed by Candra, and the air is blowing under the arrangement of the demigod Vayu. But above all these demigods, the Supreme Personality of Godhead is the chief living entity. Nityo nityanam cetanas cetananam. The demigods are also ordinary living entities, but due to their faithfulnesstheir devotional service attitudethey have been promoted to such posts. These different demigods, or directors, such as Candra, Varuna and Vayu, are called adhikari-devata. The demigods are departmental heads. The government of the Supreme Lord consists not only of one planet or two or three; there are millions of planets and millions of universes. The Supreme Personality of Godhead has a huge government, and He requires assistants. The demigods are considered His bodily limbs. These are the descriptions of Vedic literature. Under these circumstances, the sun-god, the moon-god, the fire-god and the air-god are working under the direction of the Supreme Lord. It is confirmed in the Bhagavad-gita, mayadhyaksena prakrtih suyate sa-caracaram [Bg. 9.10]. The natural laws are being conducted under His superintendence. Because He is in the background, everything is being performed punctually and regularly.
