Matsya Purana — Account of the Manvantaras: Manus
कौकुरुण्डिश्च दाल्भ्यश्च शङ्गः प्रवहणः शिवः सितश्च सस्मितश्चैव सप्तैते योगवर्धनाः //
kaukuruṇḍiśca dālbhyaśca śaṅgaḥ pravahaṇaḥ śivaḥ sitaśca sasmitaścaiva saptaite yogavardhanāḥ //
Kaukuruṇḍi, Dālbhya, Śaṅga, Pravahaṇa, Śiva, Sita, and Sasmita—these seven are indeed the enhancers of Yoga, whose presence and teaching increase yogic attainment.
This verse does not describe Pralaya directly; it catalogs seven sages identified as “yogavardhana,” emphasizing preservation and transmission of yogic knowledge across time rather than cosmic dissolution.
By highlighting “yoga-enhancing” sages, the verse implies an ethical model for kings and householders: seek guidance from realized teachers, support dharmic lineages, and cultivate inner discipline alongside worldly responsibilities.
No specific Vastu or temple-architecture rule is stated; the ritual takeaway is indirect—these named sages function as authoritative transmitters whose teachings would ground correct practice (ācāra) in rites and disciplines.
