Swedenborg discovered through profound visionary insights that the kingdom of heaven was arranged like the organs of a human body—called the “Grand Human.” This is because God’s Love and Wisdom represents infinite humanness and therefore (according to divine order) must flow into and maintain similar forms (called “correspondence”).
These God-created forms, when looked at from their true essential functions, represent a perfectly unified organic theater of reciprocal support and cooperation. The varied functions found within human bio-structure are physical metaphors of spiritual love and heavenly activity. That is why angels—and the quality of their hearts—are arranged into heavenly communities that mirror the living cooperation and reciprocal functions of human organic design (increased unity through a diversity of reciprocal love).
When the flow of God’s Holy influence becomes disharmonized because of some lack of growth and response in one of these heavenly communities, Swedenborg claimed that “there shall be straightway summoned from some earth those who will make up the deficiency, in order that the proportion may be maintained, and that in this way heaven may stand firm.” (AC 6807)
While the Lord God has many individuals from many planets throughout the great universe to choose from, good people from our own planet are regularly taken to make up this deficiency. (The reason why this process happens to so many young children is when heaven is in need of additional innocence to maintain cosmic harmony.)
In other words, the needs of heaven (and maintaining the causal integrity of correspondence between God and created beings) trump our individual and personal needs to enjoy the continued physical presence of our loved ones and friends.
One must elevate one’s mind and look at the big picture to rise above the emptiness one feels when a loved one is taken away. This is difficult because we cannot observe the spiritual world, which is the most important part of our universe. However, we should not act as though something unfortunate has happened to our lost loved ones. Those who leave us early come into a realm where they are more alive than ever and simply do not identify with our sorrow.
