Matsya Purana — Brahmā’s Four Faces
*मनुर् उवाच बुद्धेर् मोहः समभवद् इति यत् परिकीर्तितम् अहंकारः स्मृतः क्रोधो बुद्धिर् नाम किम् उच्यते //
*manur uvāca buddher mohaḥ samabhavad iti yat parikīrtitam ahaṃkāraḥ smṛtaḥ krodho buddhir nāma kim ucyate //
Manu said: “It has been proclaimed that delusion arises from buddhi; and that from it the sense of ‘I’ (ahaṃkāra) and anger (krodha) are produced. What, then, is meant by the term buddhi?”
This verse frames a creation-of-psychological-functions sequence: from buddhi arises moha (delusion), and from that ego-sense and anger—showing how manifested experience proceeds through inner faculties, a theme often used to explain bondage across cycles of creation and dissolution.
By tracing anger and ego back to delusion affecting buddhi, the verse implies that righteous rule and household life depend on clear discernment (buddhi). A king or householder must guard the intellect from moha to prevent ahaṃkāra and krodha from corrupting judgment, punishment, and daily conduct.
No direct Vāstu or ritual procedure is stated; the takeaway is foundational: ritual and temple-related duties in the Matsya Purāṇa presume disciplined buddhi, since delusion-driven ego and anger obstruct correct observance and decision-making.
