tap, tap system
Part of an apparently nameless system of "self-help" expounded by Claude M. Bristol and Harold Sherman in TNT: The Power Within You, first published in 1954. The larger system involves positive thinking and its theory posits telepathy. The authors described "TNT" as a "magnetic creative power" within people, a combination of a mental image of anything reasonable that one wants plus faith in oneself and in God (the "Great Creator"). The "tap, tap system" simply is repeated visualization of whatever one desires.
