The Discourse on Contact as Root
258.
"There are these three feelings, monks, born of contact, rooted in contact, having contact as their source, having contact as their condition.
Which three?
Pleasant feeling, unpleasant feeling, neither-unpleasant-nor-pleasant feeling.
Dependent on contact experienced as pleasant, monks, a pleasant feeling arises.
With the cessation of that very contact experienced as pleasant, whatever feeling arising from that, the pleasant feeling that arose dependent on contact experienced as pleasant, that ceases, that is appeased.
Dependent on contact experienced as unpleasant, monks, an unpleasant feeling arises.
With the cessation of that very contact experienced as unpleasant, whatever feeling arising from that, the unpleasant feeling that arose dependent on contact experienced as unpleasant, that ceases, that is appeased.
Dependent on contact experienced as neither-unpleasant-nor-pleasant, monks, a neither-unpleasant-nor-pleasant feeling arises.
With the cessation of that very contact experienced as neither-unpleasant-nor-pleasant, whatever feeling arising from that, the neither-unpleasant-nor-pleasant feeling that arose dependent on contact experienced as neither-unpleasant-nor-pleasant, that ceases, that is appeased.
Just as, monks, from the friction and combination of two sticks, heat is produced, fire is generated.
From the separation and dispersal of those very sticks, whatever heat arising from that ceases, that is appeased.
So too, monks, these three feelings are born of contact, rooted in contact, having contact as their source, having contact as their condition.
Dependent on the respective contact, the respective feelings arise.
With the cessation of the respective contact, the respective feelings cease."
