Kośa, Bala, and Maryādā: Treasury, Capacity, and Enforceable Limits (कोश-बल-मर्यादा)
उपमामत्र वक्ष्यामि धर्मतत्त्वप्रकाशिनीम् । यूपं छिन्दन्ति यज्ञार्थ तत्र ये परिपन्थिन:
upamām atra vakṣyāmi dharmatattvaprakāśinīm | yūpaṃ chindanti yajñārthaṃ tatra ye paripanथinaḥ ||
毗湿摩说道：“我在此将举一譬喻，以昭示法（dharma）之真义。人们为祭祀取木，欲制祭柱（yūpa）时，先伐所选之树；而拖曳其出林之际，凡近旁阻路之树亦必被砍倒。那些树倒下时，往往又折毁其他草木。”

Educational Q&A
Bhīṣma uses a ritual analogy to show that actions undertaken for a chosen end (even a sacred one) can produce unavoidable secondary harm; therefore dharma must be understood with attention to consequences, not merely intention.
Bhīṣma begins an illustrative comparison: to make a sacrificial post, people cut a tree and, while extracting it, also cut obstructing trees; the falling trees further damage other plants—an image of cascading effects caused by a single purposeful act.
