The Saṃyuttanikāya (S.i.134 f) relates that one day, when she was taking her siesta in Andhavana at Sāvatthi, Māra questioned her as to the origin of “a being” (satta), its creator, its origin, its destiny. Vajirā answers that there is no such thing as “a being,” apart from certain conditioned factors, like a chariot, which exists only because of its parts. Māra retires discomfited.

Vajirā’s verses are often quoted (e.g. Kvu. 240, 626; Mil. p.28; Vism.ii.593) both in the Canon and in later works, but they are not included in the Therīgāthā, nor do we know anything else about her.
