It supports the duty of orderly governance and responsible building—selecting proper measurements and auspicious times for public works or major household/temple construction to ensure stability, reputation, and continuity.
Architecturally, it prescribes a major standard of width/span (viṣkambha) at the scale of 100 yojanas; ritually/astrologically, it recommends commencing construction under Puṣya-yoga, treated as especially auspicious for durable, ‘time-honoured’ results.
