यदा संहरते चायं कूर्मोऽङ्गानीव सर्वशः । इन्द्रियाणीन्द्रियार्थेभ्यस्तस्य प्रज्ञा प्रतिष्ठिता ॥
yadā saṃharate cāyaṃ kūrmo 'ṅgānīva sarvaśaḥ | indriyāṇīndriyārthebhyas tasya prajñā pratiṣṭhitā ||
Like a tortoise draws in its limbs, the wise one withdraws senses from objects. Wisdom stands firm.
Word by word (3)
- kūrmaḥ aṅgāni iva
- — like a tortoise draws in its limbs · Kūrma = tortoise. This is one of the Gita's most celebrated analogies. The tortoise withdraws its limbs completely under its shell — not because the world has disappeared, but because the animal has chosen not to extend outward. The sthitaprajña similarly withdraws the senses from their objects: the objects still exist, but engagement is consciously retracted.
- indriyāṇi indriyārthebhyaḥ
- — the senses from sense-objects · Indriya = sense organ (from Indra, the king — the senses are the 'kings' of the body's interaction with the world). Indriyārtha = sense-object (artha = object, purpose, meaning). The withdrawal described is not sense-deprivation but sense-sovereignty: the senses obey the Self rather than ruling it.
- prajñā pratiṣṭhitā
- — wisdom is established / firmly rooted · The same closing phrase as V57 — prajñā pratiṣṭhitā. This repetition is deliberate: each mark of the sthitaprajña ends in this phrase. It functions as a refrain, deepening the portrait with each verse.
When a person can withdraw their senses from sense-objects — the way a tortoise draws in all its limbs — their wisdom stands firmly established.
A modern analogy
Imagine sitting in a loud, distraction-filled office. Most people's attention scatters to every notification, every conversation, every movement. But someone skilled in focus can close their attention down to the task at hand — not because the distractions disappear, but because they have learned to retract the mind's outward reach at will. That capacity is the tortoise's wisdom.
Take with you
- Sense-withdrawal (pratyāhāra) is not about numbing yourself — it is about choosing where you direct attention.
- The tortoise does not destroy the world to find peace; it simply retracts. You can retract too.
- Start with one sense per day: eat one meal without screens; take one walk without headphones. Train the retraction muscle.
- The senses are not enemies — they are servants. V58 teaches sense-sovereignty, not sense-warfare.
V58 introduces the concept of pratyāhāra — sense withdrawal — which Patanjali later formalized as the fifth limb of his Ashtanga Yoga system (Yoga Sutras 2.54). The tortoise (kūrma) analogy is precise: the tortoise does not destroy the external world to find protection — it withdraws into itself. Shankaracharya notes that the senses are naturally outward-moving (bahirmukha) by their very design — they are built to contact external objects. The sthitaprajña has trained the antarmukha (inward-turning) capacity: the ability to retract the senses' outward reach at will. This verse is part of the sthitaprajña portrait's shift from inner marks (V55-57) to practical disciplines (V58-68): the sensory domain, the mental domain, the social domain.
Modern parallels
Neuroscience describes the 'default mode network' (DMN) — the mind's restless outward scanning that activates when not focused on a specific task. The DMN is associated with rumination, social comparison, and anxious projection. Pratyāhāra / the tortoise discipline is the deliberate suppression of the DMN through directed attention — which fMRI studies show is associated with reduced anxiety and increased cognitive performance. Cal Newport's 'deep work' practice is a secular formalization of kūrmo 'ṅgānīva.

This verse speaks to
Where this thread continues
No sticky attachment anywhere — meeting good or bad without rejoicing or hatred. Wisdom firmly rooted.
Therefore: completely withdraw the senses from their objects in all directions. That is established wisdom.
Abandon all desires born of mental planning — without remainder — and restrain the senses completely, by the mind alone.
Those who know Me as Adhibhūta, Adhidaiva, and Adhiyajña — they know Me even at death, with unified minds.
This knowledge, more secret than all secrets, has been declared to you — reflect on it fully and act as you wish.
Mind-in-Me, devotee, worshiper, bow to Me — you will come to Me; truly I promise, you are dear to Me.
