Matsya Purana — Paurava Genealogy: Bharata
गुरुधी रन्तिदेवश्च सत्कृत्यां ताव् उभौ स्मृतौ गर्गस्य चैव दायादः शिबिर्विद्वानजायत //
gurudhī rantidevaśca satkṛtyāṃ tāv ubhau smṛtau gargasya caiva dāyādaḥ śibirvidvānajāyata //
Gurudhī and Rantideva are remembered as two men renowned for true hospitality and honorable reception of guests. And from Garga’s line there was born the wise king Śibi, his rightful heir.
Nothing directly—this verse is genealogical and ethical, preserving memory of exemplary kings and heirs rather than describing cosmic creation or pralaya.
It upholds satkṛti/atithi-sevā (honoring guests) as a hallmark of dharma: rulers and householders gain lasting repute by respectful hospitality and righteous conduct, exemplified here by Gurudhī and Rantideva.
No explicit Vastu or temple-ritual rule appears here; the ritual-ethical takeaway is the virtue of proper reception (satkṛti) as part of dharmic social practice.
