Jñāna-yoga and Karma-phala: Manu–Bṛhaspati on Akṣara and the Limits of Mantra
पापी मनुष्यका पापके द्वारा छिपाया हुआ पाप पुनः उसे पापमें ही लगाता है और धर्मात्माका धर्मतः गुप्त रक्खा हुआ धर्म उसे पुनः धर्ममें ही प्रवृत्त करता है ।।
pāpaṁ kṛtaṁ na smaratīha mūḍho vivartamānasya tad eti kartuḥ | rāhur yathā candram upaiti cāpi tathābudhaḥ pāpam upaiti karma ||
Bhīṣma said: A deluded person does not remember the sin he has committed; yet that very sin inevitably comes back to its doer when he continues in wrongdoing. Just as Rāhu moves of its own accord toward the moon, so does sin—born of one’s own actions—draw near to the foolish person and seize him. The teaching is that concealment or forgetfulness does not erase moral causality: one’s deeds return and shape one’s future conduct and fate.
भीष्म उवाच
Sin is not neutralized by being forgotten or hidden; it inevitably returns to its agent. Persisting in wrongdoing draws its consequences closer, just as Rāhu inevitably approaches the moon.
In the Śānti Parva’s instruction on righteous conduct, Bhīṣma teaches Yudhiṣṭhira about moral causality. He uses the well-known image of Rāhu eclipsing the moon to illustrate how one’s own misdeeds pursue and overtake the wrongdoer.
