By emphasizing Sandhyā and offerings like Vaiśvadeva and tarpaṇa, it points to a steady rhythm of worship and gratitude—practices that stabilize the mind and support sustained devotion.
Chandas (the Vedāṅga of metre) is explicitly referenced, underscoring correct metrical recitation as a technical foundation for Vedic chanting and ritual performance.
