वैशाखशुक्लपक्षे तु तृतीया यैरुपोषिता अक्षयं फलमाप्नोति सर्वस्य सुकृतस्य च //
vaiśākhaśuklapakṣe tu tṛtīyā yairupoṣitā akṣayaṃ phalamāpnoti sarvasya sukṛtasya ca //
ผู้ใดถืออุโบสถในวันตฤติยาแห่งปักษ์สว่างของเดือนไวศาขะ ย่อมได้ผลบุญอักษยะ คือผลไม่เสื่อมสิ้นแห่งกุศลกรรมทั้งปวง
Nothing directly—this verse focuses on vrata (fasting) in Vaiśākha and the doctrine of akṣaya (imperishable) merit, not on pralaya cosmology.
It prescribes a practical dharma for householders (and rulers as exemplars): observing a calendrical fast (Vaiśākha Śukla Tṛtīyā) that is said to yield lasting spiritual merit, reinforcing discipline, charity-oriented piety, and public religiosity.
Ritually, it highlights upoṣa on a specific tithi as a high-yield observance (akṣaya-phala). No Vāstu or temple-construction rule is stated in this verse.
