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 ||
ప్రాప్తమైనదాన్ని అనుభవిస్తూ, పరస్పర ఆధారంతో కామప్రేరక చలనం కొనసాగుతుంది. అది శుభమో అశుభమో అయినా, ఓ విప్రా, జ్ఞానులు దానిని ‘శాంతం’ అని తెలుసుకుంటారు.

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.
