The first state of the effect is meant by 'the days for bringing forth were completed' because 'bringing forth' in the spiritual sense has to do with good and truth, and means in that sense the manifestation of these, 2621, 2629. Good and truth are similar to offspring, in that they are conceived, carried in the womb, born, and after that grow to maturity. After conception the efficient, or conceived, seed starts to produce the effect. This takes place in the womb. Once these states have been completed and the time to give birth is at hand, the effect at that point begins to exist, which is called the first state of the effect. For at that point the offspring begins to act independently so to speak and to strive to reach that state which is called the state of the effect.
