यदा संहरते चायं कूर्मोऽङ्गानीव सर्वशः। इन्द्रियाणीन्द्रियार्थेभ्यस्तस्य प्रज्ञा प्रतिष्ठिता॥
yada samharate chayam kurmo'nganiva sarvashah indriyanindri-yarthebhyas tasya prajna pratishthita
Translation
When one can withdraw the senses from their objects, as a tortoise draws in its limbs, then one's wisdom is firmly established.
Commentary
The turtle analogy is brilliant — just as a tortoise can instantly retract its limbs into its shell for protection, the wise person can withdraw their senses from distracting objects at will.
