धर्म्यविजय-नियमाः
Rules for Dharmic Victory in Kṣatriya Engagement
आत्मानमात्मना हन्ति पापो निकृतिजीवन: । सज्जनोंका धर्म सदा सत्पुरुषोंमें ही रहा है। अतः उसका आश्रय लेकर उसे नष्ट न करे। धर्मयुद्धमें तत्पर हुआ जो क्षत्रिय अधर्मसे विजय पाता है
ātmānam ātmanā hanti pāpo nikṛtijīvanaḥ |
毗湿摩言：以欺诈为生的罪人，终将以自身毁灭自身。达摩常住于善人与真正高贵之士；故当依止达摩，莫使其败坏。纵在战阵之中，刹帝利若以非法（adharma）求胜——以诡计与背信——亦必自招覆亡。

Educational Q&A
That deceit as a way of life is ultimately self-destructive: a person who pursues victory or gain through adharma undermines his own welfare. Dharma is sustained among the good, so one should rely on it rather than damage it for short-term success.
In the Śānti Parva, Bhīṣma instructs Yudhiṣṭhira on kingship and dharma after the war. Here he warns that even in the context of warfare, a kṣatriya must not seek victory through fraud; such conduct rebounds upon the doer and leads to ruin.
