Purushottam is called moolapurush of kudaldeshkar Dhananjay gotri, Bharadwaj Gotri and sankhyan gotri.
Purushottam means ideal man. But this Purushottam is just a noun of a person who was devotee of Lord Shiva. He gained spiritual powers and protected his people.
His annual pilgrimage is celebrated on champa shashthi, which is also celebrated for Bhairavas of Lord Shiva. Thus we can assume that God Purushottam in Konkan is not Vishnu or his incarnation but a bhairav of Lord Shiva.
The Temple of PURUSHOTTAM is located in Gavanwadi in Parule.
