Matsya Purana — Brahmā–Gāyatrī as a Divine Pair and the Early Genealogies of Creation
*मनुर् उवाच अहो कष्टतरं चैतद् अङ्गजागमनं विभो कथं न दोषमगमत् कर्मणानेन पद्मभूः //
*manur uvāca aho kaṣṭataraṃ caitad aṅgajāgamanaṃ vibho kathaṃ na doṣamagamat karmaṇānena padmabhūḥ //
Manu said: “Alas, this indeed is most grievous—this union with one’s own offspring, O Lord. How did the Lotus-born (Brahmā) not incur fault through such an act?”
While not describing the flood directly, the verse frames a key Purāṇic concern: even cosmic creation is governed by moral order (dharma), and Manu questions how a creator-figure’s act could be reconciled with that order.
Manu’s question reflects the dharmic duty to scrutinize conduct—especially sexual ethics and lineage purity—since kings and householders are expected to uphold social order by treating such transgressions as serious faults.
No Vāstu or ritual procedure is stated in this verse; its significance is ethical and theological, setting a tone of dharma-based inquiry that later chapters can apply to rites, conduct, and sacred norms.
