वैशाखशुक्लपक्षे तु तृतीया यैरुपोषिता अक्षयं फलमाप्नोति सर्वस्य सुकृतस्य च //
vaiśākhaśuklapakṣe tu tṛtīyā yairupoṣitā akṣayaṃ phalamāpnoti sarvasya sukṛtasya ca //
凡于毗舍佉月(Vaiśākha)白半(śukla pakṣa)之第三日(Tṛtīyā)守斋者,得不坏之果报——一切善业之不失之果。
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.
