Some hold that similar analyses could be performed cross-culturally for any of the other Hindu divine vehicles, and in each case, any parallels with the values assigned to animal totems in other cultures are likely to be either coincidence, or inevitable (as in linking bulls to virility), rather than evidence of parallel development. In dialectic, this is countered by the retort that each totem or vahana, as an aspect of "ishta-devata" (or an "ishta-devata" or "asura" in its own right), has innumerable ineffable teachings, insights and spiritual wisdom; comparative analysis yields benefit, though knowledge and understanding is not served by collapsing their qualities into homogenous signification.
