“The Aṭṭhakavagga chapter of the Sutta Nipata is sometimes considered to be one of the oldest sections in the Pali Canon. The stated goal of the entire Sutta Nipata is an emphasis on the embodiment principle: how a disciple of the Buddha comports themselves in and through the world. In such engagements, one’s own views and the views of others, and the disputation between the two, becomes a rallying point for the emergence of greed, hatred, and delusion. The Buddha suggested “seclusion” as a protection from one’s own views and the need to dispute them with others.” (part of course description offered by Mu Soeng and William Edelglass)
Engagement with others is of central importance among beings; but disputations can separate one from others. Disputations and arising of greed, hatred, and delusion may result in risks to personal integrity, to ease of being, to peace of mind, or to well-being. Seclusion is, thus, advised. In fact, the more challenging interactive settings become, the more important are periods and moments of seclusion.
