11.43

rātrau tu hṛdaye mlāne saṃvṛteṣvayaneṣu ca |

yānti koṣṭhe parikledaṃ saṃvṛte sarvadhātavaḥ ||

viśleṣaṇaṃ ca sandhīnāṃ mumūrṣorupajāyate ||

agnivarṇabalabhraṃśo vegānāṃ cāpravartanam ||

At night, however, when the heart is languid and the passages are closed, / all the bodily tissues in the closed internal cavity undergo moistening. // And looseness of the joints arises in one who is about to die. // Loss of digestive fire, complexion, and strength, and non-manifestation of natural urges.
