Dr. Efrain Villegas Quintero, Honoris Causa (Master Desoto) is the founder and international director of ADEUSA - American Association of Cultural and Universal Studies, Inc. and 14 similar institutions throughout Latin America, the USA, Japan and Europe. These organizations are part of FIADASEC - International Federation of associations of Social, Ecological and Cultural Aid.

     He is a great humanist, journalist, philosopher and master of human and spiritual virtues.  He has a firm conviction that all the negative situations that our society suffers and that in general humankind suffers, is due to an unconscious and disorderly conduct. This is taken him to dedicate more than 40 years of his life to create ways to achieve a transcendental change in one's behavior. This is done by enhancing one's spiritual values, the defense and protection of all life in nature, the integral development and knowledge of oneself. Also, the incorporation of love, aid to the homeless and the unity of the family.

     This trajectory of dedication and service to humankind, has taken him to compile his work and investigations about psychology, philosophy, anthropology, human nature, esoterism, self-help and self-improvement in over 36 books. He is a great speaker and has given more than 700 lectures, workshops and seminars in Europe, the USA, Latin America, the Caribbean, Japan, Australia and the Philippines. They have all contained the teachings and human principles defined in his books.

     Due to his trajectory as instructor, guide and consular to others (who have given testimony of his magnitude), he was recognized with the distinction of Doctor Honoris Causa by the Universidad de los Pueblos in Ponce, Puerto Rico.

     The success of his labor and teachings are based on the fact that any person can experiment and give testimony of his personal experience.  His teachings have been given to hundreds of thousands of people around the world through his books and hundreds of volunteers that follow his example.

     In every association, there are instructors that are trained to teach these transforming ideas within the community and reach a true union with the Divine.  In all of his books, there is a legatos that states "If you practice the contents of these pages, you will give testimony of me".
