Matsya Purana — Account of the Manvantaras: Manus
तथैव जल्पधीमानौ मुनयः सप्त तामसे साध्या देवगणा यत्र कथितास्तामसे ऽन्तरे //
tathaiva jalpadhīmānau munayaḥ sapta tāmase sādhyā devagaṇā yatra kathitāstāmase 'ntare //
Likewise, in the Tāmasa Manvantara there were seven sages, among whom were Jalpa and Dhīmān, and the host of gods called the Sādhyas; all these have been described in the interval of the Tāmasa age.
It situates cosmic governance within a specific Manvantara (the Tāmasa period), listing its presiding sages and a deva-class (Sādhyas), implying orderly re-creation and administration between dissolutions rather than describing Pralaya directly.
Indirectly, it frames dharma within a cosmic order: sages and divine hosts uphold and transmit law and ritual in each Manvantara, which kings and householders are expected to follow as part of maintaining social and religious stability.
No explicit Vāstu or temple-rule is stated; the ritual takeaway is the Manvantara-based classification of sages and deities, useful for Purāṇic recitation, calendrical framing, and contextualizing ritual lineages.
