nirvana

In Buddhism, a Stupa is a mound-like structure, often with a spire, external carved symbols and internal ashes or other relics, used as a place of meditation. Aspects of the design and construction of stupas may represent five ancient elements, some or all of which are common to many cultures around the world: earth, air, fire, water and space.

Tibetan Buddhism has eight common types of stupas,  each referring to major events in the Buddha's life.

One of these types, the Stupa of Nirvana, by sculptor Robert Shure, was erected on November 24, 2012 at Mount Auburn Cemetery in Cambridge, Massachusetts in memory of Khenpo Lama Migmar’s late mother, Sonam Yudon.

“Each of the four sides of the stupa is engraved with the Green Tara mantra to receive healing to overcome suffering, and the Avalokiteshvara mantra to cultivate loving kindness, compassion, and wisdom. Khenpo Lama Migmar, Harvard Buddhist Chaplain,  says of the memorial, “May whoever comes into contact with this Nirvana Stupa further develop these inner qualities of love, compassion, and wisdom.” - from Mangalam Studio
