All sin is failure in spiritual perception. Spiritual perception corresponds with the momentum of a falling body in mechanics. Only in Divine mechanics it is a _rising_ body; but the same law holds good. You say truly that an action can only be called sinful when the sinner knows the higher and deliberately turns to the lower. That is true; but it is only half a truth. It is still the _lack of knowledge_ that causes sin. With the fulness of knowledge of the higher (only another way of putting fulness of spiritual perception) _must_ come the righteousness of life. It is the broken gleams, the little knowledge, which is truly a dangerous thing, for it brings responsibility, and therefore the capacity for sinning. Yet the _choice_ between good and evil fully made, is the schoolmaster to bring us to the full realisation of our nature as Sons of God. Now when Frank came over here, he was so greatly impressed by the dynamic force of spiritual perception that for the time he lost all sense of proportion and accuracy of judgment. Compared with the old earth temptations, those in his sphere seemed non-existent, whilst the temptations to goodness were enormously increased. What wonder that in the delightful sensation caused by his sense of moral and spiritual freedom from old shackles, he should exclaim with youthful fervour: "Sin is only possible in your sphere--it is unknown here!" Any communications of which he formed the channel, would of necessity be coloured by this dominant idea of his. Everything is a question of degree, and he is learning that lesson now, I find. He says: "Why do people in the earth life quote our words as if we were Delphic Oracles?" Why, indeed? But I am afraid I did much the same whilst so strongly under the Imperator influence. E. K. B.--Why is Imperator so slow in throwing off his own spiritual limitations? H. D.--I can read your mind so easily. It is quick and alert, and has already answered its own question. It is because he has a work to do on your plane amongst those who could not come in touch with a higher spiritual development. There are spiritual as well as scientific martyrs, you must remember; and he is one of them. But the Divine Economy works very beautifully here. He is not conscious of any spiritual limitation, and therefore he is happy in his work, and the martyrdom I spoke of is _unconscious_. When it becomes conscious, with him it will mean that his present plane of work is finished, and that he will be removed to another "_Form_" so soon as he is prepared to teach there. He is essentially a teacher, and a valuable one, for those who have not soared beyond his present perceptions. It is all so much more simple and reasonable than you suppose. It is these crusted old creeds that have misrepresented actual conditions, and yet they also have been, as Imperator; doing their own work amongst the people to whom they have acted as necessary stepping-stones.
