The Khanda is the symbol of the Sikhism. It reflects some of the fundamental concepts of Sikhism. The symbol derives its name from the double-edged sword (also called a Khanda) which appears at the center of the logo. This double-edged sword is a metaphor of Divine Knowledge, its sharp edges cleaving Truth from Falsehood. The circle around the Khanda is the Chakar. The Chakar being a circle without a beginning or and end symbolizes the perfection of God who is eternal. The Chakar is surrounded by two curved swords called Kirpans. These two swords symbolize the twin concepts of Meeri and Peeri - Temporal and Spiritual authority introduced by Guru Hargobind. They emphasize the equal emphasis that a Sikh must place on spiritual aspirations as well as obligations to society.
