Sons of Shri Rama – Luv & Kush and their various incarnations
“So that’s the great part of Markandeya. He took his birth later on as Buddha, then he took his birth as Adi Shankaracharya, it’s the same personality.
But he was actually the son of Rama, to begin with. He was Luv and he went to Russia and that is why they are called as Slavs. He ruled in Russia, that’s why they are called as Slavs.
Another son was Kush, who went to China, that is why they are called as Kushan.
Then they incarnated again and again, also as Hassan and Hussain, as Mahavira and Buddha, as Adi Shankaracharya and Gyaneshwara, like that.”
