Gumuhit ng isang guhit na nakaharap sa silangan, at gayundin ng guhit na kaayon ng guhit ng ekwinoks (silangan–kanluran). Ang puntong tinatawag na “agrā” ay sinasabing nasa gitna sa pagitan ng ninanais na tanda ng anino at ng tanda ng anino sa ekwinoks.

It shows that dharma and moksha-oriented life in the Purana is supported by precise knowledge (vidyā): correct orientation and time-reckoning (through shadow and equinoctial markers) safeguard the accuracy of rites and disciplined living.
While not directly a bhakti-verse, it supports bhakti-practice indirectly: accurate determination of direction and time helps perform Vishnu-oriented worship, vrata timings, and daily observances with steadiness and correctness.
Vedāṅga Jyotiṣa and chāyā-gaṇita (shadow-based measurement): drawing an east-oriented line, using the equinoctial (viṣuvat) reference, and defining a midpoint marker (agrā) for further calculation or alignment.
