In one survey conducted at Rajneeshpuram, over 70 percent of those surveyed listed their religious affiliation as "none";[1] however, 60 percent of sannyasins participated in activities of worship several times a month.[40] In late 1981 Rajneesh, through his secretary Ma Anand Sheela (Sheela Silverman), announced the inception of the "religion of Rajneeshism", the basis of which would be fragments taken from various discourses and interviews that Rajneesh had given over the years.[41] In July 1983 Rajneesh Foundation International published a book entitled Rajneeshism: An introduction to Bhagwan Shree Rajneesh and His Religion,[42] in an attempt to systematise Rajneesh's religious teachings and institutionalise the movement. Despite this, the book claimed that Rajneeshism was not a religion, but rather "a religionless religion ... only a quality of love, silence, meditation and prayerfulness".[43] Carter comments that the motivation for formalising Rajneesh's teachings are not easy to determine, but might perhaps have been tied to a visa application made to the Immigration and Naturalization Service to obtain "religious worker" status for him.[44] People followed the norms of wearing similar clothes and participating in the same activities. The people were allowed to come and go as they pleased as long as they did not hurt anybody.[45]
