Kāṣṭhīla-Upākhyāna: Rākṣasī, Spear-Śakti, and Kāśī as Śakti-kṣetra
विश्वस्तो हि यतस्त्वं वै मम सर्वेण चेतसा । ततस्त्वां गोपयिष्यामि सर्वभावेन कामुक ॥ ८४ ॥
viśvasto hi yatastvaṃ vai mama sarveṇa cetasā | tatastvāṃ gopayiṣyāmi sarvabhāvena kāmuka || 84 ||
यतः त्वं मम सर्वेण चेतसा विश्वस्तः खलु। तस्मात् त्वां सर्वभावेन सर्वथा गोपयिष्यामि, हे कामुक॥

It highlights dharmic responsibility: when trust is given wholeheartedly, one should respond with wholehearted protection and steadfast care—an ethic aligned with rakṣaṇa (guardianship) and śaraṇāgata-rakṣā (protecting one who relies on you).
Though not explicitly naming Vishnu-bhakti here, the verse mirrors a key bhakti mood: mutual trust and complete surrender/commitment (sarvabhāva). In devotion, the devotee entrusts the heart, and the Lord is praised as the protector in every way.
No specific Vedanga (Śikṣā, Vyākaraṇa, Chandas, Nirukta, Jyotiṣa, Kalpa) is directly taught in this verse; the takeaway is ethical dharma—how one should act after accepting another’s trust.
