Covert Influence of Spirits on Our Thoughts and Actions
461. How can we distinguish between our own thoughts and those the spirits suggest to us?
“When a thought is suggested, it is like a voice speaking to you. Your own thoughts usually occur to you first. This distinction is not of much practical importance to you, and it is often better not to be able to make it. Your action then has greater freedom. If you choose the right road, you do so more spontaneously, while if you take the wrong one, your responsibility will be greater.”
