Rishi Knot

In Sikhism, Kesh (sometimes Kes) is the practice of allowing one's hair to grow naturally as a symbol of respect for the perfection of God's creation. The practice is one of the Five Ks, the outward symbols ordered by Guru Gobind Singh in 1699 as a means to profess the Sikh faith. The hair is combed twice daily with a Kanga, another of the Five Ks, and tied into a simple knot known as a Joora or Rishi knot. This knot of hair is usually held in place with the Kanga and covered by a turban.

Kesh is a symbol of devotion to God, reminding Sikhs that they should obey the will of God. At the Amrit Sanchar in 1699, Guru Gobind Singh Ji explained the reason for this:

My Sikh shall not use the razor. For him the use of razor or shaving the chin shall be as sinful as incest. For the Khalsa such a symbol is prescribed so that his Sikhs can be classified as pure

Also, by not cutting hair, Sikhs honor God's gift of hair. Kesh combined with the combing of hair using a kangha shows respect for God and all of his gifts. So important is Kesh that during the persecution of Sikhs under the Mughal Empire, followers were willing to face death rather than shave or cut their hair to disguise themselves.

In modern times the trend of short hair has encroached upon this tradition. It is estimated that half of India's Sikh men have abandoned the turban and cut their hair. Reasons include simple convenience (avoiding the daily combing and tying), because their parents cut their hair and they decided to get their hair cut as well, and social pressure from the mainstream culture to adjust their appearance to fit the norm.

After the attacks of September 11, 2001, Sikhs in the West have been mistaken for Muslims and subjected to hate crimes. Balbir Singh Sodhi, a Sikh living in Mesa, Arizona, was shot to death on September 16, 2001 when he was mistaken for a Muslim.
