The sutta starts off by describing how the Buddha passes through the village of Kesaputta and is greeted by its inhabitants, a clan called the Kalamas. They ask for his advice: they say that many wandering holy men and ascetics pass through, expounding their teachings and criticizing the teachings of others. So whose teachings should they follow? He delivers in response a sermon that serves as an entry point to the Dhamma, the Buddhist teachings for those unconvinced by mere spectacular revelation.
