Based on observations made in Bulgaria in the 1970s, it is proposed that the original version of Suggestopedia for second language training, used in Bulgaria and other Eastern European countries in the late 1960s and early 1970s, differs significantly from the techniques developed later, in particular in concentration on and memorization of correct language forms. In the original method, the 4-hour class had three parts: review of the previous days' material, including singing and physical activities; presentation of a new lesson; and unconscious reinforcement/memorization of new material using relaxation largely based on yoga, with a specific sequence of music. While memory training elements of the original Suggestopedia include conventional ones, some from Soviet "hypnopedia" and/or linguistics, some invented (language dialogues), some from the original six principles of Suggestology, and some related to research on brain hemisphere functions and other communication-based approaches, it is felt the most effective are those relating to yoga: inner/outer concentration; the three intonations of the active session; the pose during the musical segment; deep, rhythmic breathing; visualization; slow-moving musical beat; the "ideal" 20-minute session; coordination of breathing with concentration and music rhythm; mind/body harmony; and a state of relaxed alertness.
