Leaves of Morya's Garden - Book 2 - Illumination (1925) - 2.3.8:
2.3.8. Not by accident do bits of the luminaries reach neighboring spheres. They are like a means of communication. These signs are neglected by modern science. The importance does not lie in that an aerolite may contain carats of diamonds, but in its significance as a psycho-magnet. By this means men can enlarge the sphere of communication. In the future coordination of matter, this quality of psycho-magnetism is important; because matter must finally blend with spirit, must become fusible, like glass. Towards the beginning of the new step of evolution a new means of healing may be applied by grouping people according to the rays of the luminaries. To go beyond the confines of the planet is the immediate objective. Not a spectator of the worlds is man, but a conscious co-worker; and his way lies not through puddles, but through the radiance of the spheres.
