June Campbell, a former Kagyu nun who is an academic feminist, acted as Kalu Rinpoche's translator for several years. In her book Traveller in Space: Gender, Identity and Tibetan Buddhism , she writes that she consented to participate in what she realised later was an abusive sexual relationship with him, which he told her was tantric spiritual practice. She raises the same theme in a number of interviews, including one with Tricycle magazine in 1996. Since the book was published she has received "letters from women all over the world with similar and worse experiences" with other gurus.
