Verumkai is the most advanced stage in the Northen style of Kalaripayattu. Here students learn how to use their bare hands to defend themselves or attack an opponent. It is at this stage that a student might be permitted by the teacher to start learning about the Marmas [vital points of the body]. A teacher will impart this knowledge only to those students who are highly disciplined not only in Kalari, but also in their everyday life and will use this knowledge both responsibly and ethically.
