Buddhism arrived in Sri Lanka in the third century BCE and the tradition of meditation practice has continued without interruption since then. When you sit in a meditation retreat here, you are doing something that monks in these forests and rock caves have been doing for over two thousand years. That context changes the practice. The most well-regarded retreat centres tend to be away from the tourist circuit. Kanduboda Meditation Centre near Colombo offers structured programmes for both beginners and experienced practitioners. The Forest Hermitage near Kandy is associated with the Theravada tradition and accepts serious practitioners for extended stays. Nissarana Vanaya in Mitirigala is one of the most respected forest monasteries in Asia — austere, serious, and profoundly effective for those who are genuinely committed.
