Emanuel Swedenborg (1688-1772) inspired Andrew Jackson Davis (1826-1910), in his major work The Great Harmonia, to say that Summerland is the pinnacle of human spiritual achievement in the afterlife; that is, it is the highest level, or 'sphere', of the afterlife we can hope to enter.
C.W. Leadbeater, a Theosophist, also taught that those who were good in their previous earthly incarnation went to a place called Summerland between incarnations [REF].
