On the Reality of Higher Worlds

Everything that leads to mediumship, to hallucinations or visions, proceeds, fundamentally, from diseased bodily organs which as it were breathe their psycho-spiritual content into the consciousness in a pathological way. All these things lie below the level of sense-experience. Imaginative Knowledge, on the contrary, lies in a realm transcending sense-perception and is developed from objectivity, not from pathological inner conditions.
