What is the meaning behind this gandik type?

[A. G. Maisey]

Yuuzan, I'm a bit handicapped with net access at the moment because I've exceeded my monthly allowance, so I don't want to use this link you've provided, however, Agni + rhino is from memory a Khymer association that does not occur in Bali-Hindu, nor in mainline Hindu belief. Again from memory, I think Agni normally uses a ram as a mount. My apologies if I'm wrong.
