1.40. When a family ruins, the etnernal duties of the family perish; when the duties perish, impiety inevitably dominates the entire family.
Shri Purohit Swami
1.40 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.
Sri Abhinav Gupta
1.35 1.44 Nihatya etc. upto anususruma. Sin alone is the agent in the act of slaying these desperadoes. Therefore here the idea is this : These ememies of ours have been slain, i.e., have been take possession of, by sin. Sin would come to us also after slaying them. Sin in this context is the disregard, on account of greed etc., to the injurious conseences like the ruination of the family and the like. That is why Arjuna makes a specific mention of the [ruin of the] family etc., and of its duties in the passage ‘How by slaying my own kinsmen etc’.
The act of slaying, undertaken with an individualizing idea about its result, and with a particularizing idea about the person to be slain, is a great sin. To say this very thing precisely and to indicate the intensity of his own agony, Arjuna says only to himself [see next sloka]:
1.26 - 1.47 Arjuna said - Sanjaya said Sanjaya continued: The high-minded Arjuna, extremely kind, deeply friendly, and supremely righteous, having brothers like himself, though repeatedly deceived by the treacherous attempts of your people like burning in the lac-house etc., and therefore fit to be killed by him with the help of the Supreme Person, nevertheless said, ‘I will not fight.’
He felt weak, overcome as he was by his love and extreme compassion for his relatives. He was also filled with fear, not knowing what was righteous and what unrighteous. His mind was tortured by grief, because of the thought of future separation from his relations. So he threw away his bow and arrow and sat on the chariot as if to fast to death.
1.40 Sri Sankaracharya did not comment on this sloka. The commentary starts from 2.10.
1.40 With the ruin of a clan, perish its ancient traditions, and when traditions perish, lawlessness overtakes the whole clan
1.40 From the ruin of the family are totally destroyed the traditional rites and duties of the family. When rites and duties are destroyed, vice overpowers the entire family also.
1.40. 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.
1.40 कुलक्षये in the destruction of a family? प्रणश्यन्ति perish? कुलधर्माः family religious rites? सनातनाः immemorial? धर्मे spirituality? नष्टे being destroyed? कुलम् कृत्स्नम् the whole family? अधर्मः impiety? अभिभवति overcomes? उत indeed.Commentary Dharma – the duties and ceremonies practised by the family in accordance with the injunctions of the scriptures.
