The Six Fields of Contact
At one time the Buddha was staying near Vesālī, at the Great Wood, in the hall with the peaked roof. Now at that time the Buddha was educating, encouraging, firing up, and inspiring the mendicants with a Dhamma talk on the topic of the six fields of contact. And those mendicants were paying attention, applying the mind, concentrating wholeheartedly, and actively listening.
