- an engram not basic is subject to sag which is to say that it may be brought to the two point zero (2.0) tone, but after a certain length of time has elapsed—from one to two days—it will be found to have sagged and to be, for instance, in a one point one ( 1.1) tone . It can be successfully lifted until it is apparently in a three point zero (3.0) tone, at which point much of its content will disappear. (DTOT, p. 114)
- any engram may be exhausted to a point where it will recede. It is temporarily and momentarily lost to the individual and apparently does not trouble him. That engram which has been exhausted in a chain without the basic having been reached will sag or reappear within twenty-four to sixty hours. (DTOT, p. 139)
