Dear Members of the List,

A friend recently asked me a rather disconcerting question (for me at least): why do Indian gods have so many arms?

My understanding was that these arms bear attributes of the god (trident, discus, severed head, etc.) to remind the devout of some parts of the god's gest, but I have not seen such explanation in Indian litterature.
What is the Indian literature exactly saying about this quite remarkable feature and where (Purāṇas, Śilpaśāstras, or elsewhere)?

Your input will be very much appreciated.
Thanks in advance.
