on the Knowledge (known as satsang) when possible. According to Galanter "satsang could be delivered to active members or to those with only a casual interest. It was something of a polemic interspersed with parables, and because members were bright and sophisticated, these discourses tended to be engaging, making use of both Hindu mythology and Western philosophy". In a study by Flo Conway and Jim Siegelman, former followers said that they had spent 32.9 hours per week in group-related processes and ritual and 19.9 hours in additional study or indoctrination (lectures, seminars, workshops etc). Vegetarianism was encouraged but not enforced except in ashrams and Divine Centers. Five "commandments" were part of the Divine Light Mission's teachings: Do not put off until tomorrow what you can do today. Constantly meditate and remember the Holy Name. Leave no room for doubt in the mind. Never delay attending satsang. Always have faith in God. In the United States, the early years of the Divine Light Mission were marked by the rapid growth of loosely affiliated local ashrams, united mainly by a shared devotion to Guru Maharaj Ji. As the DLM became more and more structured and centralized, leadership and power came to be concentrated in the Denver headquarters. According to scholars, Prem Rawat's desire to consolidate his power and authority over the U.S. movement led to increasing formalization, with rules and regulations for ashram living, standards for recruited "candidates," and pressure towards certification of the movement's teachers. According to scholars Foss and van der Lans, the teachings of Hans Ji Maharaj were minimized after 1975, and followers were expected to accept Prem Rawat as their personal savior. David V. Barrett noted that the DLM movement was often criticized for emphasizing the superiority of subjective emotional experience over intellect. The sociologists Ralph Larkin and Daniel A. Foss made similar observations in 1978. In response, the religious scholar Ron Geaves, himself a member of the movement, accused Foss and Larkin of bias. A 1981 article based on the Dutch branch of the Divine Light Mission, stated that the DLM had little philosophical background and that all its central creeds and tenets were described in the song associated with the Hindu ritual called aarti. Arti was sung to Prem Rawat in the morning and evening in ashrams. Rawat says he does not charge for teaching people the techniques of Knowledge. Related organizations that support the dissemination
