Kośa, Bala, and Maryādā: Treasury, Capacity, and Enforceable Limits (कोश-बल-मर्यादा)
स्वधर्मानन्तरा वृत्तिर्जात्याननुपजीवत: । जहत: प्रथमं कल्पमनुकल्पेन जीवनम्
svadharmānantara vṛttir jātyān anupajīvataḥ | jahataḥ prathamaṃ kalpam anukalpena jīvanam ||
毗湿摩说道：“当一个人无法依凭其出生与地位所规定的本分来维持生命时，也教有替代的生计之道。因为在困厄之时，那不得不舍弃第一要道——依自性之法（svadharma）而活——的人，被允许循其次道而生，甚至可取较低种姓的职业，以保全性命而不坠入无法无度。”

Educational Q&A
In hardship, preserving life may require setting aside the primary rule of living strictly by one’s own svadharma; the tradition allows a secondary, emergency livelihood (anukalpa), even adopting work associated with a lower varna, to avoid greater moral collapse.
Bhishma is instructing Yudhishthira in the Shanti Parva on dharma, specifically explaining the graded rules of conduct: the normal rule (svadharma-based livelihood) and the emergency exception (alternative livelihood) when normal duty cannot sustain life.
