Matsya Purana — The Pushkara Manifestation
क्रोधायाः सर्वभूतानि पिशाचाश्चैव पार्थिव जज्ञे यक्षगणांश्चैव राक्षसांश्च विशांपते //
krodhāyāḥ sarvabhūtāni piśācāścaiva pārthiva jajñe yakṣagaṇāṃścaiva rākṣasāṃśca viśāṃpate //
From Krodhā (Wrath) were born all manner of beings—indeed the Piśācas; and, O king, there also arose the hosts of Yakṣas and the Rākṣasas, O lord of the people.
It presents a creation principle: fierce classes of beings (Piśācas, Yakṣas, Rākṣasas) arise from the personified force of wrath (krodha), emphasizing moral-psychological causes in cosmic genealogy rather than describing pralaya.
By linking wrath to the birth of harmful or disruptive beings, it implicitly warns rulers and householders to restrain krodha; governance and domestic life thrive through self-control and measured discipline rather than anger.
No direct Vāstu or ritual rule is stated; the takeaway is ethical—anger is portrayed as a generative source of inauspicious forces, a theme often used to motivate purity, restraint, and auspicious conduct in ritual contexts.
