Saṃhāra-krama (The Sequence of Cosmic Dissolution) — Yājñavalkya’s Discourse
शत्रुदमन! जैसे निर्बल पक्षी सूक्ष्म जालमें फँसकर बन्धनको प्राप्त हो अपने प्राण खो देते हैं और बलवान् पक्षी जाल तोड़कर उसके बन्धनसे मुक्त हो जाते हैं
śatrudamana! yathā nirbala-pakṣiṇaḥ sūkṣma-jāle phasītvā bandhanaṃ prāpya prāṇān jahati, balavantaḥ pakṣiṇaś ca jālaṃ bhittvā tasya bandhanād vimucyante, tathā karma-janita-bandhanaiḥ baddhā nirbalā yoginaḥ sarvathā naśyanti; kintu parantapa! yoga-balena sampannā yoginaḥ sarva-bandhanebhyaḥ pramucyante. alpakāgniḥ yathā rājan vahnīḥ śāmyati durbalaḥ, ākrānta indhanaiḥ sthūlaiḥ; tadvat yogaḥ durbalaḥ prabho—rājan! yathā alpatvāt durbalo ’gniḥ sthūla-indhana-bhāreṇa dīpyamānaḥ na bhavati, api tu śāmyati, tathā nirbalo yogī mahato yogasya bhāreṇa pīḍitaḥ praṇaśyati.
毗湿摩说道：“噢，降伏仇敌者！正如羸弱之鸟陷入细密罗网，落入束缚而丧其性命；而强健之鸟则能挣断罗网，脱离羁绊——同样，那些羸弱的瑜伽行者，被自身业力所生的枷锁所缚，终将彻底败亡。然则，噢，焚敌者！具足瑜伽之力的瑜伽行者，能从一切束缚中获得解脱。大王啊，微小而孱弱的火焰，若堆压上粗重的木柴，非但不燃，反而熄灭；同样，主上啊，羸弱的修行者被大瑜伽之重所压，便会灭亡，而不得其果。”

Educational Q&A
Yoga must be undertaken with adequate inner strength and preparation; otherwise, the practitioner remains trapped in karma-born bondage and may be harmed by attempting a ‘great’ discipline without capacity. True yogic power breaks bonds and leads toward freedom.
In Shanti Parva, Bhishma instructs the king on dharma and spiritual practice. Here he uses two analogies—birds in a net and a small fire smothered by heavy logs—to contrast weak, unprepared yogins who fail with strong, well-endowed yogins who attain release.
