Bow of Vishnu is known as Saranga and Vishwakarma, the
divine architect of gods, created it. There is deep symbolism attached to bow
and arrow of Vishnu and it is not a mere weapon to annihilate demons or
enemies. Vishnu Purana states that the bow and arrow represents Indriya (senses)
and Ahamkara (ego).
Vishnu Purana further states that the numerous arrows of
Vishnu are the senses, the field of activity of intellect and the quiver is the
storehouse of actions.
The bow is the destructive-notion-of-individual existence
(tamasa Ahamkara), the aspect that is associated with the disintegrating
tendency and origin of the senses (Vishnu Purana -1.22.70).
The numerous arrows of Vishnu are the senses, the fields of
activity of the intellect. (Vishnu Purana 1.22.73)
Vishnu had a chariot drawn by four horses which according to
Mahabharata ‘moves at will life swift mind’.
