Shortly after his supreme enlightenment, the Buddha realised that someone who has nothing to respect and look up to lives in suffering. Finding no one in the whole universe who would be superior to him in virtue, samādhi, wisdom, or knowledge, he decided to live in reverence & respect to the ultimate Dhamma he had discovered. If even the Buddha felt he needs something to respect & revere, who much more would we require it?
