"Vishnu took the form of a boar; slew the 'asura' (demon), recovered the 'vedas' (sacred Hindu scriptures), and bearing up the earth out of water on his tusk, reanimated and reinstated the oppressed people"
(A Catalogue Raissone of Oriental Manuscripts)
The earliest of all the Yudhan, it can be traced back in mythology to the wild boar incarnation of Vishnu who rescued the Vedas from the demon Hiranyaksha.
Weapons synonymous with Viraha Yudhan are heavy clubs and daggers; it also forms the basis of the battle formations. In its unarmed form, it is a close-quarter, compact yet explosive combat style. Through application, the style employs misalignments and establishing a superior tactical position. In doing so, it unleashes lethal strikes to vital points utilising a wide variety of hand, foot, elbow, knee strikes which reign down on the opponent simultaneously from top to bottom.
Although the first of the styles, it should not be underestimated.
