Khāra, the general of Ravana's army. As Lord Rāma pursued Ravana, the kidnapper of his wife Sitā, Lord Rāma was met with considerable hardships at the hand of Khāra. A formidable foe, Khāra attacked Lord Rāma in different ways and manners. Each attack being vanquished by Lord Rāma to prove his purity and ability, so also we are tested in this birth, in different ways, and each accomplishment over Khāra proves our purity and step towards divinity.
