From Wikipedia: Naked Yoga is a short documentary released in 1974 and illustrates the practice of yoga in a natural setting and in the nude. The plot of this movie includes women practising yoga in Cyprus and in a studio. These visuals are interspersed with images of Eastern art, processed for "psychedelic" effect. The narrator also relates the practice to Buddhist philosophy. It was shown on television in the UK [Channel 4, in 1986 and 1988], however it has not been released to video.
This documentary/short was nominated for an Oscar in 1975, in the category Best Documentary, Short Subjects. It was written and directed by Paul Cordsen. The stars included Elizabeth Taylor-Mead and features the blues singer Alexis Korner as the narrator.
Naked Yoga had been on the list of lost films. A search for it began in 2004 by the Academy Archive's Documentary Curator, Ed Carter. After a series of letters and dead ends, Carter received a print from the film's Director of Photography, Michael Elphick, who obtained the print from a television station. The print turned out to be a 35mm Technicolor print in pristine condition. The Academy Film Archive restored the film in 2012.
This recording is from the 1988 showing of the film on Channel 4 in the UK. This copy is from VHS.
My research appears to indicate that Channel 4's transmission copy was a transfer from that last remaining print.
