Breaking the prohibition of intermarriage does not imply forcibly marrying off girls of one caste into another caste. What it means is that if a Hindu with desirable qualities such as love, character, and capacity to beget healthy offspring chooses a spouse from another caste, then such an alliance should not be condemned simply because their castes are different. Such a couple should not be considered as unworthy of cohabitation.
Permission for such mixed marriages is extremely desirable not only for the removal of birth-based caste distinction but also for the success of the re-conversion movement. It is both beneficial and essential for the consolidation of the Hindu nation.
