When inference is based not on Causation but on Uniformity of co-existence, as in inferring cloven hoofs of an animal by its horns, it is called

Inference resting on a uniform coexistence of two marks, not on cause and effect, is Samanyatodrsta.

Horns and cloven hoofs are regularly found together in the same animals.

Neither of them causes the other, so no causal link is available.

Yet the observed constant togetherness lets one mark be inferred from the other.

This general observed correlation, distinct from cause-based inference, defines Samanyatodrsta.
