Well same symbols may hold different meaning in different cultures "Swastika" is a very holy symbol in Hinduism,and when one is talking about hinduism the idea of broken cross simply DONT stand as hindu culture and its symbols etc are all thousands of years old and christianity is only 2000 yrs old.........

I dont know much about Aryans but in india it is considered that they were the outsiders which settled at northern parts of subcontinent and created holy scriptures(The Vedas)........
