At Ravana's face the vanar sprang,
Snatched from his head the kingly crown
And dashed it in his fury down
Straight at his foe the giant flew,
His mighty arms around him threw,
With strength restless swung him round
And dashed him panting to the ground,
Unharmed amid the storm of blows,
Swift to his feet Sugriva arose.
Again in furious fight they met,
With streams of blood their arms were wet,
Each grasping his opponent's waist.
Thus with their branches interlaced,
Which, crimson with the flowers of spring,
From side to side the breezes swing,
In furious wrestle you may see,
The Kinsuk and the Seemal tree.
Kushti, or Indian pit wrestling, derives from Persian rules of wrestling. In Hindu culture, wrestling has evolved into a spiritual path. Competitions are organized around the akhara, a combination of dormitory and gym, enforcing sexual abstinence and a diet of unleavened flat bread, eggs, milk, butter, and almonds, along with special exercises (vyiyam) to improve strength, agility, and tactical command of the body. The wrestlers adhere to strict rules of hygiene, including set rules on when and how to defecate, and take precautions against seeing, even by accident, animals having sex. The wrestlers live and train together, seeking strength and purity through the practice of wrestling. Hanuman, the Hindu monkey deity, is thought to preside over every akhara.
--The Ramayana, trans. R.T.H. Griffith
Matches occur on mounds of sand moistened with ghi (clarified butter). There are eleven categories, based on each wrestler's weight. Before wrestling, the men aggressively beat their hands against their muscles to put their opponents on notice. A wrestler wins when he pins his opponent's back to the ground. The prizes, such as a mace and a shield, symbolize the ancient tradition of warrior heroism.
