The Kalama Sutta (Sanskrit: Kalama Sutra) is a Buddhist sutta in the Anguttara Nikaya of the Tipitaka. It is often cited by Mahayana and Theravada Buddhists alike. Kalama sutta is also called Buddha’s charter of free inquiry

In this sutta, Gautama Buddha passes through the village of Kesaputta and is greeted by the people who live there: the Kalamas. The Kalamas greet the Buddha and ask for advice. According to the Kalamas, many wandering holy men and ascetics pass through the village, expounding their teachings and criticizing others’. The Kalamas ask the Buddha whose teachings they should follow. In response, he delivered a sutta that serves as an entry-point to Buddhist beliefs to those unconvinced by revelatory experiences.

The Kesariya Stupa, situated at the place where Buddha delivered the Kalama Sutta [edit] Discerning Religious Teachings The Buddha instructs the Kalama People on which basis one should decide which religious teaching to accept as true. The Buddha tells the Kalamas to not just believe religious teachings because they are claimed to be true by various sources or through the application of various methods and techniques. He urges that direct knowledge from one’s own experience should be called upon. He notably does not, however, say (contrary to popular misconception) that his own teachings should not be accepted or not accorded trust[citation needed]: rather, he counsels that the words of the wise should be heeded and taken into account when deciding upon the value of a teaching.
