यदा संहरते कामान् कूर्मोडज़ानीव सर्वशः । तदा<5<त्मज्योतिरचिरात् स्वात्मन्येव प्रसीदति
yadā saṁharate kāmān kūrmo'ṅgānīva sarvaśaḥ | tadā ātmajyotir acirāt svātmany eva prasīdati ||
Devasthāna said: “When a person withdraws all desires, just as a tortoise draws in its limbs on every side, then the inner light of the Self soon becomes calm and clear, resting in one’s own true being.”
देवस्थान उवाच
Restrain and withdraw desires completely—like a tortoise retracting its limbs—so that consciousness becomes steady; then the inner light (ātmajyotiḥ) quickly settles into serenity in the Self.
In the didactic setting of Śānti Parva, Devastāna instructs on inner discipline: the speaker uses a vivid simile (tortoise withdrawing limbs) to describe how a seeker should draw the mind back from sense-objects, leading to calm self-abidance.
