In the cycle of material activities, the material body resembles the wheel of a mental chariot. The ten senses [five for working and five for gathering knowledge] and the five life airs within the body form the fifteen spokes of the chariot’s wheel. The three modes of nature [goodness, passion and ignorance] are its center of activities, and the eight ingredients of nature [earth, water, fire, air, sky, mind, intelligence and false ego] comprise the rim of the wheel. The external, material energy moves this wheel like electrical energy. Thus the wheel revolves very quickly around its hub or central support, the Supreme Personality of Godhead, who is the Supersoul and the ultimate truth. We offer our respectful obeisances unto Him.
The cycle of repeated birth and death is figuratively described herein. As stated in Bhagavad-gītā (7.5):
prakṛtiṁ viddhi me parām
yayedaṁ dhāryate jagat
The entire world is going on because the living entity, who is part and parcel of the Supreme Lord, is utilizing the material energy. Under the clutches of the material energy, the jīvātmā is revolving on the wheel of birth and death under the direction of the Supreme Personality of Godhead. The central point is the Supersoul. As explained in Bhagavad-gītā (18.61):
hṛd-deśe ’rjuna tiṣṭhati
“The Supreme Lord is situated in everyone’s heart, O Arjuna, and is directing the wanderings of all living entities, who are seated as on a machine, made of the material energy.” The material body of the living entity is a result of the conditioned soul’s activities, and because the supporter is the Supersoul, the Supersoul is the true reality. Every one of us, therefore, should offer respectful obeisances to this central reality. One should not be misguided by the activities of this material world and forget the central point, the Absolute Truth. That is the instruction given here by Lord Brahmā.
