Sukta 22

For invoking ‘light’ (jyotis) to bring clear perception and ordered conduct, and to protect against confusion, impurity, and hostile influences—often with a dawn-time (uṣas) emphasis.

No. The verses themselves work as a luminous protective-healing charm; at most, practitioners may add simple purity acts like washing or sprinkling clean water.

In Vedic symbolism, ‘go’ can indicate cattle/wealth and also a manifest field of nourishment and radiance; here it seals the hymn’s aim of purity plus flourishing in the properly timed (svásara) order.
