स्वभावयुकत्या युक्तस्तु स नित्यं सृजते गुणान्‌ । ऊर्णनाभिर्य था सूत्र विज्ञेयास्तन्तुवद्‌ गुणा:,आत्मा अपने स्वरूपमें स्थित रहकर ही सदा गुणोंकी सृष्टि करता है। ठीक उसी तरह, जैसे मकड़ी अपने स्वरूपमें स्थित रहती हुई ही जाला बनाती है। मकड़ीके जालेके ही समान समस्त गुणोंकी सत्ता समझनी चाहिये

svabhāvayuktyā yuktaḥ tu sa nityaṃ sṛjate guṇān | ūrṇanābhiḥ yathā sūtraṃ vijñeyās tantuvad guṇāḥ ||

อาตมันผู้ประกอบด้วยกำลังแห่งสภาวะของตน ย่อมก่อกำเนิดคุณ (คุณะ) อยู่เนืองนิตย์ ดุจแมงมุมซึ่งดำรงอยู่ดังเดิม แต่ปั่นเส้นใยและถักทอใยจากตนเอง ฉันนั้น คุณทั้งหลายพึงรู้ว่าเป็นดุจเส้นด้าย

Educational Q&A

The Self remains established in its own nature, while the guṇas (sattva, rajas, tamas) arise and operate like threads spun from a spider. Recognizing this helps one detach from fluctuating mental states and act with steadiness and discernment.

In the Shanti Parva’s instruction on liberation and right understanding, Bhishma teaches Yudhishthira using a vivid analogy: as a spider produces a web without ceasing to be itself, so the guṇas manifest from the underlying Self/nature, explaining change in experience without change in the essential Self.
