The principles of Nokku Varmam are rooted in the concept of pressure points, which are specific areas on the body that, when manipulated, can cause pain, discomfort, or even death. Practitioners of Nokku Varmam aim to target these pressure points to disable their opponents quickly and efficiently. The art involves a deep understanding of human anatomy, as well as the application of various techniques, including strikes, thrusts, and joint locks.
