Lord Muruga's weapon 'Vel' (spear) :
Gaze at the small size 'vel', in picture No.7a, close your eyes. Then open your eyes and concentrate on any object and close your eyes again. The object can be seen in the body. This will give yogic powers. The practioneer can get more creative knowledge from this God.
Gazing at the bigger 'vel' in picture No.7b, gives absolutism in knowledge.

No. 7a
