This reading of the Kalama Sutta is from the Anguttara Nikaya. Here, the Buddha travels to a village of the Kalamas called Kesaputta. The people there, having heard the teachings of many wandering ascetics, express their doubt to the Buddha as to whom to believe. In the ensuing dialogue, the Buddha encourages them to not simply address teachings on their face value, but to examine any teaching from the point of view of their own personal experience.
