The starting point of this work is the blessed command of the Truthful Informer: “When you see that everyone is infatuated with their own opinion, leave people aside and busy yourself with that which is beneficial to you in this world and the hereafter!” This command has placed such a responsibility upon its humble addressee that it has become necessary to dedicate the time period of 1974–2018, during which this work was conducted, entirely to understanding and explaining a lifestyle based on divine unity, and no other intention or effort has ever been in question.
