LAUGHTER
  1. Laughter plays a definite role in therapy. It is quite amusing to see a preclear, who has been haunted by an engram which contained great emotional charge, suddenly relieve it, for the situation, no matter how gruesome it was, when relieved, is in all its aspects a subject of great mirth. Laughter is definitely the relief of painful emotion. (DMSMH, p. 121)
  2. this laughter is the reversing of charge residual in the locks which depended for their fear content or antagonistic content upon the basic engrams. (DTOT, p. 99)
