In 1974 articles about the Millenium '73 festival and the Divine Light Mission phenomenon were published. They were highly critical of Prem Rawat and the "Knowledge", understandably so.
Research by Stephen A. Kent, published in "From Slogans To Mantras" has revealed the extent of the hostility to Prem Rawat in the 1970's underground press. It was to the counter-culture readers that most of the proselytisation was going on and they had a much greater knowledge of the methods, success and results of the practice of "Knowledge". It was particularly appropriate that the Fifth Estate was so vitriolic in this short piece as it was their reporter, Pat Halley, who was nearly murdered by Mahatma Fakiranand for the shaving cream pie incident in the following year.
Prem Rawat's "Knowledge" has three parts: regularly listening to his speeches, doing voluntary work for organisations serving him or donating money and daily meditation correctly practicing the four techniques he recommends. The techniques are so simple it's hard to see how they could be practiced incorrectly. First technique ("Divine Light") involves sticking your thumb and middle finger on your eyeballs (NB: with eyes closed) and your index finger between your eyebrows. Second technique: ("Heavenly Music") poking your thumbs into your ears and listening. Third technique: ("Holy Name") thinking about your breathing (NB: continue to breathe). Fourth technique: ("Nectar") curling your tongue backwards and tasting. Rawat's father taught slightly different techniques but either way it's difficult to see how these could produce the benefits claimed for them especially as Rawat claims His Knowledge is the only method of attaining real happiness and love in this life.
