The Blessed Buddha once explained Contemplation of Feeling thus: How, Bhikkhus & Friends, does one reflect on feelings as reactions? When feeling a pleasant feeling, one notes and clearly understands: I feel a pleasant feeling! When feeling a painful feeling, one notes & understands: I feel a painful feeling. When feeling a quite neutral & neither-painful-nor-pleasant feeling, one notes and understands: I feel a neutral neither-painful-nor-pleasant feeling. When feeling a worldly pleasant feeling, one notes and understands: I feel a worldly pleasant feeling. When feeling a pleasant feeling not of this world, one notes & understands: I feel a pleasant feeling not of this world. When feeling a worldly painful feeling, one notes and understands: I feel a worldly painful feeling. When feeling a painful feeling not of this world, one notes and understands: I feel a painful feeling not of this world . When feeling a worldly neutral feeling, which is neither-painful-nor-pleasant, one notes and understands: I feel a worldly neither-painful-nor-pleasant feeling. When feeling a neutral feeling not of this world, one understands: I feel a neutral feeling not of this world. This is how a Bhikkhu abides reflecting on feelings just as responses or reactions to various forms of sense contact...
Comments: Worldly feeling arises from sense contact with this world... Unworldly Feeling arises from meditative withdrawal from the world... The cause of the emergence of momentary feeling is sense contact! The cause of the ceasing of this feeling is the ceasing of that contact! Contact is the meeting of 3: Object, sense-organ and consciousness!
