Strength of the locks
Dreadlocks are more than just a symbolic statement of disregard for physical appearance. Both Eastern and Western Traditions hold that bodily, mental and spiritual energies mainly exit the body through the top of the head and the hair. If the hair is knotted, they believe, the energy remains within the hair and the body, keeping a person more strong and healthy.
An excellent example from Western tradition is biblical Samson, whose unsurpassed strength was lost when Delilah cut off his *seven* locks of hair. In classical India, all students on the spiritual path were directly enjoined by their scriptures to develop Dreadlocks as a means to detach them from physical vanity and aid them in the development of bodily strength and supernatural mental and spiritual powers
