Bhagavad Gita Chapter 2 Verse 58 भगवद् गीता अध्याय 2 श्लोक 58 यदा संहरते चायं कूर्मोऽङ्गानीव सर्वशः। इन्द्रियाणीन्द्रियार्थेभ्यस्तस्य प्रज्ञा प्रतिष्ठिता।।2.58।। हिंदी अनुवाद - स्वामी रामसुख दास जी ( भगवद् गीता 2.58) ।।2.58।।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। Shri Vaishnava Sampradaya - Commentary Lord Krishna gives the analogy of a turtle which withdraws its limbs inside. Similarly when one is able to keep their senses from pursuing sensual objects of mundane pleasure by withdrawing the senses inside and who also consciously reflects upon the soul within, such a one is sthita- prajna situated in the perfect knowledge of transcendent meditation. There are four stages in developing to this platform each of which develops backwards from its preceding stage. The difficulty in following this is revealed by Lord Krishna in the next verse.
