This tuft that you see in this boy's head will be there on every student's head.
The Scientific reason behind this is that it attracts Cosmic energy and affords enlightenment. It is said that knotting this applies little pressure on the brain and helps one to improve concentration and mind control and improves memory.
Now this TUFT has become a FASHION STATEMENT with many..especially artists and musicians. Originally only the Priests and Temple Priests had this !
