Matsya Purana — Solar–Lunar Motions
तथा कामकृतेनेह सेवनाद्विषयस्य च इत्येतैः कारणैः सिद्धाः श्मशानानीह भेजिरे //
tathā kāmakṛteneha sevanādviṣayasya ca ityetaiḥ kāraṇaiḥ siddhāḥ śmaśānānīha bhejire //
Likewise, through acts here driven by lust, and through indulgence in sense-objects, people—by such causes—are destined for, and resort to, the cremation-grounds (śmaśāna) here as their lot.
This verse is not about Pralaya; it is an ethical-karmic warning that lust-driven conduct and indulgence in sense-objects lead to inauspicious outcomes symbolized by association with cremation-grounds.
It supports the Matsya Purana’s dharma emphasis on self-restraint: a householder (and especially a king) should govern desire and sensory indulgence, since unchecked kama is presented as a cause of social and personal degradation and inauspicious living conditions.
The verse does not prescribe Vastu or temple rules directly; ritually, it uses the cremation-ground (śmaśāna) as a marker of inauspiciousness, implying that purity, restraint, and avoidance of degrading habits are prerequisites for auspicious ritual life.
