The sikha is a long tuft or lock of hair left on the top or back of the shaven head of an orthodox Hindu male. During childhood, many Hindu boys have their heads shaved in a special ritual. Sometimes, a lock of hair is left at the crown and allowed to grow throughout the man’s life. Although traditionally all Hindus were required to wear a sikha, today it is seen mainly among ascetic monks. The sikha signifies one-pointed spiritual purpose and is always knotted, except under what circumstances? Discuss
