"Smart people" are people with strong wisdom and deep knowledge. The five covers are greed, shame, sleep, regret and doubt. A person who has a deep understanding of the Five Covers should not only hear the Buddhist thought, but also make various observations and behaviors through the wisdom gained by hearing and thinking after hearing the Buddhist thought, so as to break my insistence or even break my insistence and prove that Bodhi is famous. This is a person who has a deep understanding of the Five Gais.
