Matsya Purana — Pitṛ Worlds
योगिनी योगमाता च तपश्चक्रे सुदारुणम् प्रसन्नो भगवांस्तस्या वरं वव्रे तु सा हरेः //
yoginī yogamātā ca tapaścakre sudāruṇam prasanno bhagavāṃstasyā varaṃ vavre tu sā hareḥ //
The Yoginī—also called Yogamātā—undertook exceedingly severe austerities. Pleased with her, the Blessed Lord (Hari) granted her a boon, and she chose a boon from Hari.
This verse is not about pralaya; it highlights tapas (austerity) as a spiritual force that draws divine grace and results in the granting of a boon.
It underscores disciplined self-control and devotion—virtues praised for householders and rulers alike—implying that sustained dharmic practice and restraint can lead to divine favor and success in righteous aims.
No direct Vāstu or temple-architecture rule appears here; the ritual takeaway is the efficacy of tapas and devotion as a means to obtain divine sanction for subsequent rites or vows.
