The book that tells us about Pajapati, the Therigatha, is part of the Pali canon. It's a collection of poems written by the first nuns and is considered to be perhaps the oldest work ever written by women. I'd like to share a couple of these poems that were written by Pajapati's disciples. They give a better picture of what it was like for the women of that era to be able to have the freedom and opportunity to follow a spiritual path, to have support for it, and to be able to attain their own awakening. The first poem is actually one by Pajapati.
All pain is understood The cause, the craving is dried up.
The Noble eight-fold way unfolds. I have reached the state where everything stops. I have been mother, son, father, brother, grandmother, knowing nothing of the truth I journeyed on. But I have seen the Blessed one. This is my last body and I will not go from birth to birth again.
