Matsya Purana — Saptamī Sacred Bath and the Mṛtavatsābhiṣeka Rite for Pacifying Misfortune an...
*श्रीभगवानुवाच पुरा कृतानि पापानि फलन्त्यस्मिंस्तपोधन रोगदौर्गत्यरूपेण तथैवेष्टवधेन च //

The Blessed Lord said: “O treasure of austerity, sins committed in the past bear fruit in this very life—appearing as disease, as misfortune and wretchedness, and also as the death of one’s beloved.”
This verse does not describe Pralaya; it teaches karmaphala—how past sins manifest as suffering (disease, misfortune, and bereavement) within worldly life.
It reinforces ethical governance and disciplined living: a king or householder should avoid pāpa (harm, injustice, neglect of dharma) because its results can appear as public/private calamity—illness, poverty, and loss—urging righteous conduct, charity, and restraint.
No Vāstu or temple-construction rule is stated here; the ritual takeaway is moral-causal—perform dharmic acts and avoid sinful conduct to prevent adverse karmic outcomes.
