The deities you have named are VERY even tempered and kind, although they should still be treated with respect despite their statues being unconsecrated.

Approach your local temple or sintua and ask them if they provide 'sending off' services for discarded statues.

The correct method of disposal is to burn them, but there are certain protocols involved and this is not something a lay worshipper can do on their own.

Pm me if you r from kl.
