12. The happiness of the perfected spirits is not a state of idle contemplation, which would be, as has frequently been pointed out, merely a state of eternal and wearisome uselessness. Spirit-life, at every degree, is, on the contrary, a state of constant activity, though an activity exempt from fatigue. The most perfect felicity of that life consists in the enjoyment of all the splendors of the creation, which human language is incapable of describing, and of which the most exuberant human imagination would fail to form the remotest conception; —in the knowledge and comprehension of all things; in the absence of every sort of suffering, physical and moral, in an interior satisfaction, a serenity of soul that nothing can disturb; in the pure and perfect affection which unites all beings who, through the absence of evil and inferior spirits, are beyond the reach of disappointment or annoyance; and, above all, in the vision of God and in the understanding of the sublime mysteries of existence that are unveiled only to those who have rendered themselves worthy of such initiation. The happiness of fully purified spirits consists also in the joyful exercise of the functions with which they have been charged. They are the Messiahs, the Messengers of God, for the transmission and the execution of God’s volitions; they accomplish great missions, preside over the formation of worlds and the maintenance of the general harmony of the universe, glorious posts at which spirits only arrive as the direct result of their perfection. Only those who have reached the highest grade of perfectibility are admitted to have knowledge of the secrets of God, and receive the direct inspiration of God’s thought, of which they are the immediate representatives.
