In this Indus sign, a pictograph of a pack has been used to portray a small area which forms the target. Then, the arrow is seen to touch the target. Hence, this is an ideograph for the verb to strike.

Comment:
A pack would often have been wrapped in hide in order to protect the contents during transport. Therefore, the pack symbol is associated with hide. In inscription Ad-6, a drum skin is struck. The drum skin would have been made from hide.
