Matsya Purana — The Episode of Madhu and Kaiṭabha: Gunas
यः परो योगमतिमान् योगाख्यः सत्त्वमेव च रजसस्तमसश्चैव यः स्रष्टा विश्वसंभवः //
yaḥ paro yogamatimān yogākhyaḥ sattvameva ca rajasastamasaścaiva yaḥ sraṣṭā viśvasaṃbhavaḥ //
He who is Supreme—whose intelligence is Yoga itself, who is known as Yoga; who is also Sattva, and likewise Rajas and Tamas; and who, as the Creator, is the source from whom the universe arises.
It identifies the Supreme as the very source of cosmic origination and as the ground of the three guṇas (sattva–rajas–tamas) through which creation (and by implication dissolution) operates.
By teaching that the same Supreme underlies all guṇas, it supports guṇa-aware ethics: a ruler or householder should cultivate sattva (clarity, restraint, truth) and govern rajas and tamas rather than be driven by them.
No direct vāstu or ritual rule is stated; the takeaway is foundational theology—ritual and temple practice are meaningful because the Supreme pervades the guṇas and is the ultimate source of the cosmos honored in worship.
