impurities of mind and, as a result of the process of cultivating a pure mind, freedom from suffering. Goenka described Vipassana meditation as an experiential scientific practice, in which one observes the constantly changing nature of the mind and body at the deepest level, through which one gains a profound self-knowledge that leads to a truly happy and peaceful life. Courses start with observation of natural (i.e. not controlled) breath, which allows the mind to become concentrated, a practice called Anapana. This concentration prepares one for the Vipassana practice itself which, in this tradition, involves observing bodily sensations with equanimity and becoming progressively more aware of the interconnection between mind and body. Theoretical component Given that teachings of Vipassana in the Burmese traditions are derived from the Abhidhamma Pitaka (which, according to Theravadin commentarial tradition and Goenka, was expounded by the Buddha to Sariputta), and although some Burmese teachers advocate that Vipassana and Abhidhamma study cannot be separated, Goenka invites students to consider the theoretical aspects of his teachings, advising, though, that the important aspect of the technique is its practice. Students are free to accept his theoretical background or to reject any part of it that they find objectionable. Goenka reports the words of the Buddha as follows (emphasis in the original): Meditation Centres The Vipassana Meditation Centres that Goenka helped to establish throughout the world offer 10-day courses that provide a thorough and guided introduction to the practice of Vipassana meditation. There are no charges for either the course or for the lodging and boarding during the course. These courses are supported by voluntary donations of people who want to contribute for future courses. Only donations made at the end of the course go towards paying for future new students. The organisation of the centres are decentralized and self-sufficient and may be run by volunteers of varying experience, which may account for differences in attitudes and experiences. In an effort to provide a more uniform experience in all of the centres, all public instruction during the retreat is given by audio and video tapes of Goenka. When asked about problems related to growth and expansion, Goenka stated: Students practising Goenka's Vipassana technique at the meditation centres are asked to agree to refrain from practising any other religious or meditative practices for the duration of the course. Concerning practices of other religions, Goenka stated: "Understand. The names of many
