Diakka
A term used by Andrew Jackson Davis to signify wicked, ignorant, or undeveloped spirits. It is believed that at death no sudden or violent change takes place in the character and disposition of an individual. Those who are mischievous, unprincipled, sensual, during their lives remain so, for a time at least, after they die. Hudson Tuttle says, "As the spirit enters the spirit world just as it leaves this, there must be an innumerable host of low, undeveloped, uneducated, or in other words, evil spirits." There is, indeed, a special sphere or plane for these diakka, where they are put on probation. It is they who are responsible for the fraud and trickery often witnessed at seánces; they not only deceive the sitters, but the medium as well. The way to avoid their influence is to live a pure, refined, and religious life, for these evil spirits are naturally attracted to those whose minds most resemble their own.
