Trumpet communications
From Bahai9
Mesmerism or Trumpet Communications[edit]
"The planets and stars have no spiritual effect in the earthly world, but the parts of the universe which are in endless space are closely connected with each other. This connection produces material effects. Outside of the Bounty of the Holy Spirit all that thou hearest concerning mesmerism or trumpet communications from the dead are sheer imagination."
