AsIyati
Āsīyati [etymology doubtful; Trenckner Miln page 422= ā + śyā to freeze or dry up, but taken by him in meaning to thaw, to warm oneself; Müller P.Gram. 40 same with meaning "cool oneself"; Morris' JPTS 1884, 72 as ā + śrā or śrī to become ripe, come to perfection, evidently at fault because of śrā etc. not found in Sanskrit More likely as a passive formation to be referred to ā + śī as in āsaya, i.e. to abide etc.] — to have one's home, one's abode or support in (locative), to live in, thrive by means of, to depend on Miln 75 (kaddame jāyati udake āsīyati i.e. the lotus is born in the mud and is supported or thrives by means of the water).
āsīyati Mv iii.86.3 ( vs ), apparently 3 sg. pass. of ās, impersonal, it is sat, one sits ; but the passage is obscure to me.
