Quite secluded from sense pleasures, secluded from unwholesome states, one enters and dwells in the first jhāna, which is accompanied by thinking and examining and filled with the rapture and happiness born of seclusion. One drenches, steeps, saturates, and suffuses one’s body with this rapture and happiness born of seclusion, so that there is no part of one’s entire body which is not suffused by this rapture and happiness. (DN 2.77)
