The basis is Vipassana meditation, as taught by Gautama the Buddha, combined with śamatha meditation. At the heart of its practical side is systematic cultivation of attention to the sensations of the breath (Anapanna), and bodily sensations. The practice is reinforced by detailed explanations, illuminating the workings of the mind, helping to identify the factors challenging continuous stable attention, and offering efficient solutions (both conceptual and practical) for dealing with them.
