Mediumship

What is the purpose of true mediumship?
Who do you think are the Higher Immortals?
Why are the ordinary demonstrations of spirit return unsatisfying and of little use?
What do you think the higher Schools of Spirit teach?
With whom only can a medium get in touch in Spirit?
Is there any good to be derived by developing psychic sensitiveness? Why?
Why is it better to seek first the Kingdom of God?
