How do we live by the spirit and not the flesh?

There is as much superstition and bigotry on the subjects of spiritualism and spirit communion amongst spirits, as there is amongst those in the flesh—nor is it to be wondered at when we consider with what prejudices people are sent out of our world into the next world and how little change they experience in their mode of life and surroundings. The spirit world is so material to their senses that they cannot realise the existence of spirit at all, still less that they themselves are spirits.
