The destruction of our kindred means the destruction of the traditions of our ancient lineage, and when these are lost, irreligion will overrun our homes.
Translated by Shri Purohit Swami
In the destruction of a family, the immemorial religious rites of that family perish; on the destruction of spirituality, impiety indeed, overwhelms the whole family.
Translated by Swami Sivananda
