Matsya Purana — Account of the Manvantaras: Manus
साध्या विश्वे च रुद्राश्च मरुतो वसवो ऽश्विनौ आदित्याश्च सुरास्तद्वत् सप्त देवगणाः स्मृताः //
sādhyā viśve ca rudrāśca maruto vasavo 'śvinau ādityāśca surāstadvat sapta devagaṇāḥ smṛtāḥ //
The Sādhyas, the Viśvedevas, the Rudras, the Maruts, the Vasus, the two Aśvins, and the Ādityas—these, likewise, are remembered as the seven classes of divine hosts (deva-gaṇas).
It does not describe Pralaya directly; it classifies the divine orders that operate within cosmic administration—an organizing cosmology often taught alongside creation narratives.
By naming the principal deva-hosts, it supports ritual and dharmic orientation: kings and householders perform offerings and observances with correct knowledge of the divine recipients and cosmic hierarchy.
Architecturally it is indirect, but ritually it is relevant: these deities commonly appear as recipients in yajñas and festival worship, informing which deva-classes may be invoked in temple rites and consecrations.
