In plain words
Even for the unchanging Self, results are spoken of as if they belonged to it—just as victory is attributed to a king who sits still—because both action and mental activity are other than the Self.
Close to the Sanskrit
Even in the unchanging one, a result is appropriate, like victory and the like in a king, because of the two reasons: action and mental cognition are both other than the Self.
