Devaśarmā–Vipula Dialogue on Ahorātra–Ṛtu as Moral Witnesses (अनुशासन पर्व, अध्याय ४३)
अथवा पौरुषेणेयं न शक््या रक्षितुं मया
athavā pauruṣeṇeyaṁ na śakyā rakṣituṁ mayā
毗湿摩说道：“否则，单凭人力我无法守护此事。因陀罗——富贵之主，素以多变形相闻名——被传为威力无边。故我唯有依凭瑜伽之力，纵使面对因陀罗，也要护她周全。”

The verse contrasts ordinary human exertion (pauruṣa/puruṣārtha) with yogic or ascetic potency (yogabala), implying that certain protections or vows cannot be upheld by mere worldly strength when confronted with divine-level power; one must rely on inner spiritual discipline and higher means.
Bhīṣma reflects on his inability to safeguard a certain matter through ordinary effort alone. Anticipating opposition even from Indra—renowned for power and many disguises—he resolves to take refuge in yogic strength to ensure protection.
