संसारे जायमानस्य भ्रियमाणस्य देहिनः नश्यते देह एवात्र नात्मनो नाश उच्यते //
saṃsāre jāyamānasya bhriyamāṇasya dehinaḥ naśyate deha evātra nātmano nāśa ucyate //
Pour l’être incarné, né dans le saṃsāra et emporté par son cours, seul le corps périt ici ; la destruction du Soi (ātman) n’est pas affirmée.
It frames dissolution in philosophical terms: what truly “perishes” is the body, while the ātman is not subject to destruction—implying that even in cosmic change, the Self remains untouched.
By distinguishing body from Self, it supports steadiness in dharma: a king or householder should act responsibly without despair or fear of death, understanding that bodily loss is not the annihilation of the true Self.
No direct vastu/ritual rule is stated; the takeaway is doctrinal—ritual and right conduct are oriented toward realizing the imperishable ātman rather than merely preserving the perishable body.
