Ajima Hariti Temple

"Mother Goddess Ajima Hariti, also known as Sitala, protectress of children. The Yaksi Hariti was present at a sermon given by Sakyamuni Buddha on Gopuccha Prabat. She promised to serve the dharma, protect the Boudhanath stupa and guard prepubescent children."

As I recall there are more nuances to the story but as I have heard the Buddha asked that offerings be made to her daily, and so they are in this main shrine.

"Hārītī (Sanskrit), also known as Kishimojin in Japanese:鬼子母神, is a Buddhist goddess for the protection of children, easy delivery, happy child rearing and parenting, harmony between husband and wife, love, and the well-being and safety of the family. Women without children also pray to Kishimojin to help them become pregnant.

Originally, Kishimojin/ Hariti was a cannibalistic demon. She had hundreds of children whom she loved and doted upon, but to feed them, she abducted and killed the children of others. The bereaved mothers of her victims pleaded to Śākyamuni Buddha to save them.

Śākyamuni stole Aiji, youngest of Kishimojin's sons, and hid him under his rice bowl. Kishimojin desperately searched for her missing son throughout the universe. Finally, she pleaded with Shakyamuni for help. The Buddha pointed out that she was suffering because she lost one of hundreds of children, and asked if she could imagine the suffering of parents whose only child had been devoured. She replied contritely that their suffering must be many times greater than hers, and vowed to protect all children.

Kishimojin became the goddess of easy birthing and the protection and parenting of children.

Some stories describe her as an aspect of Kannon. She is also sometimes identified with the Hindu goddess Kali.

Pancika was her consort, and he fathered her children. He was one of the 28 Yakṣa generals in the army of Vaiśravaṇa (Bishamonten).

In Gandhara, depictions of Hārītī take on many attributes of the Greek goddess Tyche; like Tyche, she is often depicted holding a cornucopia and dressed in Greek attire."
