The root of all things
Majjhima Nikāya 1 of 152
Translation by Bhikkhu Bodhi read by Roland Kitchen
In this sutta the Buddha analyses the thinking process of four different types of people, the untaught ordinary person, the Disciple in higher training the Arahant and the Tathagata. The sutta details the progression from perception and delight because of misunderstanding the true nature of perception to directly knowing, dispassion and release through full understanding.
