Śrī Kṛṣṇā at various instances in the Mahābhārata showed his various divine opulences in myriad ways. But, several people used the word Māyāví for dismissing it as something tāmasī or non-divine. Moreover, generally, as far as I understand, the word Māyāví is mostly used in a negative connotation only.
Also, there's a concept of a divine person Siddha (here to be taken as, one in possession of the eight great
perfections - Aṣṭa Siddhīs ).
Generally if one looks explicitly in material sense, both, a Māyāví & a Siddha can portray or exhibit the "miraculous activities" that are considered supernatural or not achievable for a normal human in any Yuga perhaps.
So, how may one distinguish between these two,
a Māyāví & a Siddha?
Does scriptures talk about this difference / indifference, in any way?
