The wisdom of the appearance of the spirit in the body is this: the human spirit is a Divine Trust, and it must traverse all conditions, for its passage and movement through the conditions of existence will be the means of its acquiring perfections.

That world beyond is a world of sanctity and radiance; therefore, it is necessary that in this world he should acquire these divine attributes. In that world there is need of spirituality, faith, assurance, the knowledge and love of God. These he must attain in this world so that after his ascension from the earthly to the heavenly Kingdom he shall find all that is needful in that eternal life ready for him.

The human spirit may be likened to the bounty of the sun shining on a mirror. The body of man, ... grows and develops through the animal spirit.

In the beginning of his human life man was embryonic in the world of the matrix. There he received capacity and endowment for the reality of human existence. The forces and powers necessary for this world were bestowed upon him in that limited condition. In this world he needed eyes; he received them potentially in the other. He needed ears; he obtained them there in readiness and preparation for his new existence. The powers requisite in this world were conferred upon him in the world of the matrix.

This perfected body can be compared to a mirror, and the human spirit to the sun. Nevertheless, if the mirror breaks, the bounty of the sun continues; and if the mirror is destroyed or ceases to exist, no harm will happen to the bounty of the sun, which is everlasting. This spirit has the power of discovery; it encompasses all things.

The mind and spirit of man advance when he is tried by suffering. ... so suffering and tribulation free man from the petty affairs of this worldly life until he arrives at a state of complete detachment.

Therefore, in this world he must prepare himself for the life beyond. That which he needs in the world of the Kingdom must be obtained here. Just as he prepared himself in the world of the matrix by acquiring forces necessary in this sphere of existence, so, likewise, the indispensable forces of the divine existence must be potentially attained in this world.
