"If a spiritual intelligence discovers itself only to us by the economy of the material universe, then man's spiritual part is concerned only with the safety and happiness of his body. The truth of this is verified by observation ; for the most enlarged and successful exertions of his intelligence have been for the benefit of our duration here: All his fine talents are bemisted whenever he launches into the spiritual world, and he can do nothing but toss over incoherent material imagery which he knows not to apply how, where, or to what. When he can discover a Supreme Mind engaged in spiritual exercises, or in any thing above the care of the universe, then let him also turn his attention to spiritual life and exercises, over and above the attention due to his present existence."
