179. There are levels of love and wisdom, consequent levels of warmth and light, and also levels of atmosphere. Without a knowledge that there are levels, what they are and what they are like, what is to follow will be incomprehensible, since there are levels in everything that has been created; therefore they exist in every form. Consequently, I need to discuss levels in this part of Angelic Wisdom.

We can tell clearly from the angels of the three heavens that there are levels of love and wisdom. Angels of the third heaven so surpass angels of the second heaven in love and wisdom, and these in turn so surpass angels of the farthest heaven, that they cannot live in the same place. Their levels of love and wisdom mark them off and separate them. This is why angels of the lower heavens cannot climb up to angels of the higher heavens, and why if they are allowed to climb up they do not see anyone or anything around them. The reason they do not see anyone is that the love and wisdom of the higher angels is on a higher level, a level beyond their perception. Every angel actually is her or his love and wisdom; and love together with wisdom is human in form because God, who is love itself and wisdom itself, is human.

Occasionally I have been allowed to see angels of the farthest heaven go up to angels of the third heaven. When they managed to get there, I heard them complain that they could not see anyone; and yet they were surrounded by angels. They were afterwards told that these angels had been invisible to them because they could not perceive their love and wisdom, and it is love and wisdom that give angels their human appearance.

65. The uses of all things that have been created ascend by degrees from the lowest created forms to mankind, and through mankind to God the Creator from whom they originate. The lowest created forms are, as we said above, each and every constituent of the mineral kingdom, which are substances of various kinds, composed of stony, saline, oily, mineral and metallic materials, and covered with soil resulting from plant and animal matter disintegrating into a fine dust. In these lie the end in all uses that originate from life, and also their beginning. The end in all uses is the endeavor to effect them, and their beginning is the force acting as a result of that endeavor. These are the end in and the beginning of the uses of the mineral kingdom.

[2] Intermediate created forms are each and every constituent of the plant kingdom. These are grasses and herbs of every kind, shrubs and bushes of every kind, and trees of every kind. Their uses exist to serve each and every constituent of the animal kingdom, both the lower ones and the higher. They nourish these, gratify them, and enliven them. They nourish their bodies with their substances, gratify their senses with their taste, smell and beauty, and enliven their affections. An endeavor to serve in these ways is present in them also from life.

[3] The highest created forms are each and every constituent of the animal kingdom. The lowest forms in it are called worms and insects, the intermediate ones birds and beasts, and the highest ones human beings. For every kingdom has in it its lowest, intermediate, and highest constituents, the lowest existing to serve the intermediate, and the intermediate existing to serve the highest.

Thus do the uses of all things that have been created ascend in turn from the lowest created forms to mankind, which is the highest in order.
