Adhyātma–Adhibhūta–Adhidaivata Correspondences and the Triguṇa Lakṣaṇas (Śānti-parva 301)
इन्द्रियाणीह सर्वाणि स्वे स्वे स्थाने यथाविधि । अनीशत्वात् प्रलीयन्ते सर्पा हतविषा इव,फिर सुषुप्ति-अवस्था होनेपर विषय-ज्ञानमें असमर्थ हुई सम्पूर्ण इन्द्रियाँ अपने-अपने स्थानमें उसी प्रकार विधिवत् लीन हो जाती हैं, जैसे विषहीन सर्प (भयसे) छिपे रहते हैं
indriyāṇīha sarvāṇi sve sve sthāne yathāvidhi | anīśatvāt pralīyante sarpā hataviṣā iva ||
Bhīṣma berkata: “Di sini semua indria, masing-masing pada tempatnya sendiri dan menurut tatanan yang semestinya, mereda dan melebur karena tak lagi berkuasa untuk bertindak—bagaikan ular yang telah hilang bisanya, bersembunyi tanpa daya mencelakai. Dalam tidur lelap, indria-indria menjadi tak mampu menangkap objeknya dan karena itu menarik diri ke landasan masing-masing.”
भीष्म उवाच
When the senses lose operative power—most clearly in deep sleep—they withdraw into their own bases and cease engaging with objects. The simile of venomless snakes highlights that without their effective power, the senses cannot ‘bite’ the world of sense-objects; this supports the ethical ideal of sense-restraint and inner withdrawal.
In Śānti Parva’s instruction, Bhīṣma is explaining a psychological/ontological process: during suṣupti (deep sleep) the faculties of perception and action become incapable of object-knowledge and therefore subside into their respective seats, illustrated by the image of snakes rendered harmless by loss of venom.
