Developed and voiced by Dr. Thomas Budzynski while at the University of Colorado Medical Center and as Clinical Director of the Biofeedback Institute of Denver.

The cassette series of six 19 to 30 minute tape sides is designed to augment biofeedback training. The series constitutes a complete training sequence beginning with exercises designed to develop an awareness of muscle sense, continuing with the development of self-statements which will produce a "cultivated relaxation" pattern, and ending with a program of applied stress management. Because of its completeness, the cassette series can be used without biofeedback; however, the training with feedback equipment compliments the tapes.

Originally develped by Dr. Budzynski over a three year period, the cassette program provides the client with a successful strategy for the production of deep relaxation during biofeedback training, and motivates the client to practice regularly at home or at work.
