Kāṣṭhīla-Upākhyāna: Rākṣasī, Spear-Śakti, and Kāśī as Śakti-kṣetra
सत्यं ब्रह्मस्वरूपं हि तत्सत्यमभिधीमहि । सत्यं तु सर्वदा विप्र मंगलं मंगलप्रदम् ॥ ५८ ॥
satyaṃ brahmasvarūpaṃ hi tatsatyamabhidhīmahi | satyaṃ tu sarvadā vipra maṃgalaṃ maṃgalapradam || 58 ||
ସତ୍ୟ ହିଁ ବ୍ରହ୍ମସ୍ୱରୂପ; ତେଣୁ ଆମେ ତାହାକୁ ‘ସତ୍ୟ’ ବୋଲି କହୁ। ହେ ବିପ୍ର, ସତ୍ୟ ସଦା ମଙ୍ଗଳମୟ ଏବଂ ମଙ୍ଗଳଦାୟକ।
Suta (narrating the teaching within the Uttara-Bhaga context)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: bhakti
It equates satya (truth) with Brahman’s very nature, making truthfulness not merely ethics but a direct alignment with ultimate reality; hence it becomes inherently auspicious and merit-giving.
Bhakti rests on sincerity and integrity; by affirming truth as Brahman-nature, the verse implies that truthful speech and conduct purify the devotee and make worship, japa, and vrata spiritually fruitful.
It reinforces the dharmic discipline of truthful speech (a key practical application of śāstric conduct); while not a technical Vedanga lesson, it supports correct mantra-japa and ritual efficacy through satya and śauca (purity).
