The Fourth Sphere is the first Spiritual Sphere. To reach this sphere the soul must have mastered the spiritual degree of feeling. Here the soul is completely free of the Earth and has also discarded all material feelings. The soul can make itself one with all life and now gets to know all the laws of life.
The atmosphere itself is characterized by a beautiful purplish glow. The inner light of the spiritual inhabitants shines like a summer sun. From this sphere the soul is united with the twin soul. In happiness they now go on together forever.
