I have seen in my society that cousin marriage is not encouraged. What is the basis of this view? I am asking about scriptural injunctions. Has Smritis categorically disapproved it?
I have seen these questions, which all discussed the exceptional case of South India, where it is allowed.
How can Sage Kashyap marry daughters of Daksha, even they are parallel cousins?
Cross-cousin marriage and hinduism
Cross-cousin(mother's sister's daughter) marriage? [Please refer to questions I linked]
I am from the Eastern part of India. It is not allowed here. From the above discussions, I understood that it is not permitted in North India also. So, in general, why it is not allowed?
