It distinguishes the fruits of three purifying disciplines: homa specifically pacifies pāpa (sin), while svādhyāya culminates in the highest inner peace (śānti), with tapas supporting both as disciplined effort.
Though framed as moksha-dharma and purification, it supports bhakti indirectly: a purified mind (through homa and tapas) and a steady, scripture-saturated intellect (through svādhyāya) become fit for sustained remembrance and worship of the Lord.
Svādhyāya implies disciplined Vedic recitation and study, which practically relies on Śikṣā (phonetics) for correct chanting and Vyākaraṇa (grammar) for accurate understanding; homa points to correct ritual procedure aligned with Kalpa (ritual manuals).
