Devi's Upa-Purana, Mahabhagavata mentions that once Shiva and Lalita (call Kali if you like), had desired to switch their roles, and then Lalita assumed a masculine form, and Shiva transformed himself into a goddess. Lalita's male form was Krishna and Shiva in female form was Radha. Their residence is Goloka'. They do Rasa-Krida in that form.đ
So, the Krishna of Goloka is NOT Vishnu's incarnation. Krishna of Goloka is Devi in male form, and Radha in goloka is Shiva.đ
Vishnu's incarnation Krishna was the one who manifested on Earth during Dwapara yuga as son of Devaki to establish righteousness and de-burden the Earth.
can u answer whether it's true or not?đł
