A dasasīlamātā (Pali) or dasa sil mata (Sinhala: දස සිල් මාතා) is an Eight- or Ten Precepts-holding anagārikā (lay renunciant) in Buddhism in Sri Lanka, where the newly reestablished bhikkhuni (nun's) lineage is not officially recognized yet.
They are usually expected to work in viharas, essentially as maids to ordained bhikkhus, while receiving training and the opportunity to practice.
However, some dasa sil matas have struggled and managed to establish monasteries of their own, where women have the opportunity devote themselves to spiritual training and practice.
In Burma, an eight precept nun is addressed as thilashin or sayalay, whereas a fully ordained woman is called a rahan-ma ("female monk").
[1][2] Sri Lanka's dasa sil matas are recognized by their shaven heads and yellow robes.
