Kāṣṭhīla-Upākhyāna: Rākṣasī, Spear-Śakti, and Kāśī as Śakti-kṣetra
प्राप्तं निषेवन्नन्योन्यं वर्तते कामकारकम् । शुभं वाप्यशुभं विप्र तं तु शांतं विदुर्बुधाः ॥ ६६ ॥
prāptaṃ niṣevannanyonyaṃ vartate kāmakārakam | śubhaṃ vāpyaśubhaṃ vipra taṃ tu śāṃtaṃ vidurbudhāḥ || 66 ||
जो प्राप्त हो उसी का सेवन करते हुए, परस्पर आश्रय से काम का प्रेरक प्रवाह चलता रहता है। वह शुभ हो या अशुभ, हे विप्र, बुद्धिमान उसे ‘शांत’ (निवृत्त) जानें।

It points to the mechanics of kāma (desire): by repeatedly indulging in what one obtains and remaining in reciprocal entanglements, desire keeps operating and yields both good and bad karmic outcomes; the wise aim for śānti—quieting the desire-drive rather than feeding it.
By implying that chasing results (śubha/aśubha) sustains desire, it supports a bhakti stance of offering outcomes to the Lord and cultivating inner calm—reducing self-centered craving so devotion becomes steadier and less transactional.
No specific Vedāṅga (like Vyākaraṇa or Jyotiṣa) is directly taught; the practical takeaway is ethical-psychological discipline: observe how indulgence sustains desire and practice restraint and equanimity toward outcomes.
