In the destruction of a family, the immemorial religious rites of that family perish; on the destruction of spirituality, impiety, indeed, overcomes the whole family.

When a family is destroyed, its ancient family traditions perish; and when dharma is lost, adharma overcomes the whole family.

Arjuna widens his argument to society. When families are destroyed, their long-standing customs, kuladharma, the rites and duties handed down through generations, are lost. Without dharma to sustain it, the family falls under adharma, disorder. In the world of the epic, the family was the bearer of religious and social life, so its destruction meant more than loss of lives. Arjuna is speaking from within the values of his time, and the verse shows that his concern extends to the continuity of tradition, not only to individuals.
