When Linden returned from the Vietnam war, he resumed his college studies but changed his major from Electrical Engineering to Psychology. The war had decisively changed him. He learned the hard way about the reality of war and what it did to people. He was appalled by the horrendous cost in human life both military and civilian,  and the physical and psychological toll it inflicted on the wounded and survivors. He learned a valuable lesson to respect all life, even his enemy.  His long journey as a wounded warrior and healer had begun.

Linden graduated summa cum laude from Assumption College in Worcester, Massachusetts with a Master’s Degree and Certificate of Advance Graduate Studies in Psychology and Counseling. He was a licensed Marriage and Family therapist specializing in clinical hypnosis. He worked in private practice, community mental health, and in psychiatric hospitals. He also used his knowledge of hypnosis to treat patients suffering from physical pain and a variety of life threatening medical conditions.

Linden discovered the spiritual power of healing through his hypnotic experiences and altered states of consciousness.  He realized that hypnosis like shamanic healing had the power to open doorways to otherworldly realities and healing powers beyond our contemporary understanding of the mind.
