Boudha Stupa (Nepali: बौद्धनाथ; Newari: खास्ति चैत्य); or Jarung Kashor (Let it be done, Slip of the tongue)[2](Standard Tibetan: བྱ་རུང་ཀ་ཤོར།, Wylie: bya rung ka shor), also known as Khasti Chaitya or Khāsa Chaitya, is a stupa and major spiritual landmark[3] seen as the embodiment of the enlightened mind of all the Buddhas,[2][3][4] located in Boudhanath, within the city of Kathmandu, Nepal.

[5] Built in the northeast of Kathmandu Valley in a Tamang village surrounded by rice paddies,[3] the stupa gave birth to the origins of Tibetan Buddhism.

The route then turns directly south, heading over the Bagmati River to Lalitpur and the ancient Malla Kingdom in Patan.

Along with Swayambhunath and Namo Buddha, it is one of the most visited pilgrimage sites for devout Buddhists, which also attracts tourists to the Kathmandu area.

Built at the main northern entrance to the Boudha Stupa is a shrine to the Dharma protectress Mammo Pukkasi, known as the fierce Hariti or Ajima to local Newari Buddhists.

Second, the Newars legend of the stupa's origin attributes it to King Dharmadeva's son, Manadeva as atonement for his unwitting patricide.

Astrologers suggested that a sacrifice with a male candidate having ‘swee-nita lachhyan'(स्वीनिता लछ्यन), or thirty-two perfections, should be performed.

[12] During the time of its construction, the place was struck with a drought and the people managed to abate the scarcity of water by collecting the droplets of dew.

She was cast into the human realm, where she was reborn into a family of Kathmandu Valley poultry farmers, and named Samvari.

I will build a support for the wisdom-mind of all the buddhas, my own yidam, a place for beings to accumulate immeasurable merit, a great stūpa whose essence is the Tathāgatas’ relics.

She immediately began building the stupa with bricks loaded by her four sons and a servant, carried by an elephant and a donkey.

Local Newar people became concerned about the size of the stupa, and how it would reflect on members of the king's court who were not building bigger supports for the Dharma and roots of merit.

The king refused to change his decision, and explained how "Let it be done" (Jarung) "slipped from his tongue" (Kashor).

[2][13][14] After rediscovering the translation of the terma, Shakya Zangpo came to Nepal in search of the stupa but found only an abandoned mound.

A painting of Samvari is on the rear of the Pukkasi or Mammo Hariti shrine at Boudha Stupa where a pond with ducks is depicted with a lady taking care of them.

The Nepalese government was criticised for its slow pace in reconstructing quake-damaged heritage structures such as temples, with many left unrepaired.

[17][18] The Tamang community, an ethnically Tibetan group in Nepal, has been living around Boudhanath for many centuries and they still own land surrounding the area of Boudha Stupa.

Today his descendants still have a role regarding the stupa though management is now devolved to the Shree Boudha Nath Area Development Committee which was established as part of the UNESCO requirements for the protection of the World Heritage Site Monument Zone.
