Zoroastrianism believes that a person is born into a particular religion according to the Divine Plan and, therefore, acquires a particular type of Khoreh. It is for this fundamental reason that Zoroastrianasim does not encourage conversion or inter-communal marriages, in the belief that the clash of different Khorehs would disturb the Divine Law....Is it justifiable???

Humanity is ONE.........mixing of races, religions or what u call Khoreh, only enriches the gene pool. That will lead to better offspring. These are all narrow short sighted traditional beliefs of conventional religions!
