BASIC
  1. the first incident (engram, lock, overt act) on any chain. (HCOB 15 May 63)
  2. the first experience recorded in mental image pictures of that type of pain, sensation, discomfort, etc. Every chain has its basic. It is a peculiarity and a fact that when one gets down to the basic on a chain, (a) it erases and (b) the whole chain vanishes for good. Basic is simply earliest. (HCOB 23 Apr 69)
