Knowledge is a term used by Shri Hans Ji Maharaj (Hans Rawat) to denote a formulation of four specific techniques that were imparted in a process of initiation. The term continues to be used by two of Shri Hans Ji Maharaj's sons, Satpal Rawat and Prem Rawat. Origins These techniques have some similarities to techniques in Sant Mat derived movements and may be derived from Surat Shabd Yoga. Additionally, Kranenborg writes that the techniques of Knowledge originated from the Surat Shabda Yoga or Sant Mat, the Path of the Sound Current, and that some of the techniques are related to the 'japa-' or mantra-yoga which are similar to some techniques of Transcendental meditation and the Hare Krishnas. The website "Maharaji.org" (1999) included the traceable story of "Masters" that, according to Prem Rawat, referred to the techniques of Knowledge since 1780, including Totapuri, Anandpuri Ji, Dayal Ji, Swarupanand Ji, and his father Hans Ji Maharaj. Descriptions According to the Dutch religious scholar and Christian minister Reender Kranenborg and the American religious scholar J. Gordon Melton, these techniques are secret and were originally called "Light", "Sound", "Name" or "Word" and "Nectar" but Prem Rawat now refers to them as the 1st, 2nd, 3rd and 4th techniques. Prem Rawat asks practitioners to promise "not to reveal these techniques to anyone", but says to "let other people go through their own journey... [so] they, too, can have the techniques when they are ready." Kranenborg and Melton provide differing details of them in their writings but agree on a general description of the practices, referring for some of those, to tantric practices or sabda-brahman meditation. Another description including the details of the four techniques of knowledge is provided by Dr. Daniel Kriegman who describes the process for receiving Knowledge utilized by the Divine Light Mission in the early 1970s. Michael Drury, describes these techniques as helping the practitioner to develop "a deep and spiritual self-knowledge." Experience Jeffrey K. Hadden cites Prem Rawat in saying that "Knowledge is a way to be able to take all your senses that have been going outside all your life, turn them around and put them inside to feel and to actually experience you... What you are looking for is inside of you." Glen Whitaker, former national organizer of Elan Vital in the UK, said "That which we seek is already within us. The process of reaching it is one
