‘I have enjoyed your dear letter, and it makes me feel thankful. I have often thought that freed spirits probably lead a life of delightful activity; none of the “burdens of the flesh” to fetter them down. The idea of spirits preaching to spirits is, however, rather new to me. But there seems nothing against it, and probability rather in its favour. That verse in St. Peter, to which you refer, certainly strengthens the idea; for the disciples are permitted in so many ways to follow their Master.
