Lack of Dharmashikshan is the root cause of Hindus becoming rationalists !
Due to education on their own religion, lakhs of Muslims all over the world are always ready to sacrifice everything for the sake of their religion. On the other hand, due to lack of Dharmashikshan (Education on Dharma), Hindus become rationalists and they start proving their own Dharma wrong !
It is only Dharma which can unite Hindus !
Other than Dharma among the Hindus in India, language, religious and Holy festivals, customs, traditions, attire, etc. vary as per the States. Hence, it is only the Dharma which can unite Hindus. At least now, it is essential for Hindus to realise the importance of Dharma and unite.
