There are ten classical fighting forms in Sanatan Shastar Vidiya termed 'Yudhan' (combat forms) or 'Pentra' (tactical deployments). The first six Yudhan are known as 'Khat Ang' (six limbs). These six Yudhan are based upon characters from Indian mythology that possess animal forms. When integrated, they form the seventh limb - the leopard 'parjog' (application). Beyond these are three more advanced forms referred to as 'Dev Ang' (limbs of the gods), which are based upon Shiva and his consort, the Devi (also known as 'Shakti', 'Durga', 'Chandi', etc.).
The ten collective forms in themselves are not considered as the fighting art of Shastar Vidiya; they are repositories of ancient tactics and techniques required for particular situations and environments. Each form is a continuum from the previous, building upon the skills and attributes of its predecessor.
Those wishing to attain the battlefield skills of Shastar Vidiya are expected to train individually in these fighting forms, gradually progressing through them systematically. In time, through constant practice with the underlying science of 'parjog' (application), these techniques and tactics integrate into one homogenous seamless whole. A Shastar Vidiya warrior at this level of skill is able to respond to any situation or physical attack naturally and spontaneously in the most efficient and versatile manner. Together with application of tactics and intelligent strategy, the warrior is formidable.
All Shastar Vidiya fighting forms have both unarmed and armed applications; they can be done individually, in pairs, groups or armies. A unique characteristic that distinguishes Shastar Vidiya from other more familiar fighting forms of Eastern martial arts is that there are no sequential movements; rather they are governed by very precise principles.
What follows are brief descriptions that provide an insight into the diversity of the ten Yudhan of Shastar Vidiya.
