Matsya Purana — The Karmic Cause of Purūravas’ Beauty and Fortune
उपवासफलात्प्राप्तं राज्यं मद्रेष्वकण्टकम् उपोषितस् तथाभ्यङ्गाद् रूपहीनो व्यजायत //
upavāsaphalātprāptaṃ rājyaṃ madreṣvakaṇṭakam upoṣitas tathābhyaṅgād rūpahīno vyajāyata //
By the merit born of fasting, he obtained an untroubled kingship among the Madras; yet, because he had fasted and then performed oil-anointing (abhyaṅga), he was born lacking in beauty.
This verse does not address Pralaya; it focuses on karma-phala—how fasting yields political prosperity, while other actions can shape bodily outcomes like beauty.
It frames kingship as morally conditioned: a ruler’s stability (“thornless” rule) is gained through disciplined vows like fasting, reminding householders and kings that personal observances influence public fortune.
The ritual note is abhyaṅga (ceremonial anointing/oil-unction), indicating that ritual acts—especially when paired with austerities—are treated as causally potent in Purāṇic ethics, even when not directly linked to Vāstu or temple rules.
