Safi Nidiaye, born in 1951, is a bestselling author in the realm of psycho-spiritual life-help. From the practice of meditation, she developed her "body-centred heart work" in the early 1990s, a method of self-perception situated somewhere between non-professional and therapist circles that has now become well established. She conveys this body-centred aspect in seminars in several languages, and trains interested laypeople and therapists in this method.
