Kalaripayattu the martial art form of Kerala is regarded as the oldest and most scientific in the world. Training in combat is given at the katari (training school), The principles of kalari education stipulate that training in martial arts begins with an oil massage of the body which goes on until the body is agile and supple. Feats like chattam (jumping), attam (running), marichil (somersault) etc. are then taught, followed by lessons in the use of weapons such as daggers, swords, spears, maces, the bow and arrow and so on.
Kalaripayattu training aims at the ultimate co-ordination of the mind and body. The traditional training in a kalari includes specialisation in indigenous medical practices as well. Kaiaris are also centres of religious worship, The general guidelines to be followed in Kaiaripayattu demand that once the course is complete, a person should undergo oil massage and engage in the practice of the feats at least once a year to help him keep in shape.
