Swami Vivekananda has claimed that the great Vedic scholar Sayanacharya, who wrote a commentary on the Vedas, had reincarnated as the infamous Max Muller.
Does this claim have any basis?
From what the Swami said, it appears that he guessed that Muller was the rebirth of Sayanacharya because Muller used Sayanacharya's commentary of the Vedas in his translation of the Vedas.
This is like claiming that Aurangzeb was the rebirth of Duryodhana because both were evil, killed people, oppressed Dharma, etc.
