When, like the tortoise which withdraws all its limbs on all sides, he withdraws his senses from the sense-objects, then his wisdom becomes steady.

Swami Sivananda

And when one fully withdraws their senses from the objects of the senses, just as a tortoise withdraws its limbs, then their wisdom remains established.

When one is able to draw their senses away from the objects of sense on all sides, like a tortoise draws in its limbs, then their wisdom is firmly established.

Swami Adidevananda

He who can withdraw his senses from the attraction of their objects, as the tortoise draws its limbs within its shell—take it that such a one has attained perfection.

Shri Purohit Swami

जिस तरह कछुआ अपने अङ्गोंको सब ओरसे समेट लेता है, ऐसे ही जिस कालमें यह कर्मयोगी इन्द्रियोंके विषयोंसे इन्द्रियोंको सब प्रकारसे समेट लेता (हटा लेता) है, तब उसकी बुद्धि प्रतिष्ठित हो जाती है।

Swami Ramsukhdas

कछुवा अपने अंगों को जैसे समेट लेता है वैसे ही यह पुरुष जब सब ओर से अपनी इन्द्रियों को इन्द्रियों के विषयों से परावृत्त कर लेता है? तब उसकी बुद्धि स्थिर होती है।

Swami Tejomayananda
