A poster writes "This samudrolanghana [loss of caste due to seafaring] was made up fear so that Brahmins learned in Vedas don't move out of the country and lose the Veda sakha."
However, this is all quaint now because Hindu priests are clamoring to come to the US - not just for religious visas but citizenship. The center of Hinduism has also started shifting to the US.
Given that this samudrolanghana rule is not followed by many Hindus (priests included), have any Hindu acharyas commented on the amendability of dharma shastras in general?
