The Account of Kāṣṭhīlā (Kāṣṭhīlā-ākhyāna) within the Mohinī Narrative
वसिष्ठ उवाच । मोहिनीवचनं श्रुत्वा देवी संध्यावली विभो । धैर्यमालंब्य तां तन्वीं ब्रूहि ब्रूहीत्यचोदयत् ॥ ३७ ॥
vasiṣṭha uvāca | mohinīvacanaṃ śrutvā devī saṃdhyāvalī vibho | dhairyamālaṃbya tāṃ tanvīṃ brūhi brūhītyacodayat || 37 ||
வசிஷ்டர் கூறினார்—விபோ, மோகினியின் சொற்களை கேட்ட தேவியான சந்த்யாவலி தைரியத்தைத் தாங்கி, அந்த மெலிந்த பெண்ணை மீண்டும் மீண்டும் தூண்டினாள்—“சொல், சொல்!”

It highlights dhairya (steadfast courage) as a prerequisite for receiving sacred instruction—Saṃdhyāvalī composes herself and actively prompts Mohinī to disclose what must be spoken.
Indirectly, it models the devotional attitude of earnest inquiry (jijñāsā): the listener does not remain passive but respectfully urges the speaker to reveal the teaching, a common setup for transmitting bhakti-oriented dharma and tirtha-mahātmyas.
No specific Vedāṅga (like Vyākaraṇa or Jyotiṣa) is taught in this verse; the practical takeaway is conversational discipline in śāstra—clear speaker-listener roles and repeated prompting to elicit a complete instruction.
