And when he withdraws, As a tortoise withdraws its limbs from all sides, The senses from the objects of the senses, His wisdom (prajñā) is firmly established.
When, like a tortoise retracting its limbs, he withdraws his senses completely from sensuous objects, his insight is sure.
(58) And when he draws in on every side his senses from their proper objects as a tortoise [might draw in] its limbs—firm-stablished is the wisdom of such a man.
2.58 And when this one fully withdraws the senses from the objects of the senses, as a tortoise wholly (withdraws) the limbs, then his wisdom remains established.
2.58 When one is able to draw his senses from the objects of sense on every side, as a tortoise draws in its limbs, then his wisdom is firmly set.
2.58 When, like the tortoise which withdraws on all sides its limbs, he withdraws his senses from the sense-objects, then his wisdom becomes steady.
