Matsya Purana — The Pushkara Manifestation
रोदनाद्रवणाच्चैव रुद्रा इति ततः स्मृताः निरृतिश्चैव शंभुर्वै तृतीयश्चापराजितः //
rodanādravaṇāccaiva rudrā iti tataḥ smṛtāḥ nirṛtiścaiva śaṃbhurvai tṛtīyaścāparājitaḥ //
From (their) causing lamentation and also bringing about melting (or dissolution), they are therefore remembered as “Rudras.” And among them, one is called Nirṛti, and indeed another is Śambhu; the third is Aparājita (the Unconquered).
It links the term “Rudra” with functions associated with distress and dissolution—suggesting Rudras as forces that preside over breakdown, melting away, or transformative destruction rather than purely benevolent creation.
Indirectly, it frames destructive power as a legitimate cosmic function; in dharma terms, rulers and householders are reminded to respect auspicious/inauspicious forces (Śambhu/Nirṛti) through restraint, protection of order, and appropriate rites to avert disorder.
While not architectural, it is ritually relevant: names like Śambhu and Aparājita are used in Shiva-invocation and protective (aparājita) prayers, and Nirṛti is associated with pacificatory rites to neutralize inauspicious directions/forces.
