Guanyin / Avalokiteśvara, Buddha of Compassion

This Buddhist deity is originally known as Avalokiteśvara or Padmapani from the Pali language. Avalokiteśvara evolved into 觀音菩薩 (Guānyīn Púsà) or simply 觀音 (Guānyīn or Kuan Yin) in China.

In Tibet the name is Chenrezig. In Myanmar/Burma it's Lokanat or Lokabyuharnat. In Thailand it's Lokesvara. In Sri Lanka, the name is Nātha.

In the image on this scroll, Guanyin is holding a 淨瓶 (jìng píng). A 淨瓶 is a bottle or vessel that contains Buddhist holy water. Or, some will suggest that this symbolically holds all of the water of the earth. This water has properties that heal and rejuvenate all living things.
Note that I said "goddess" but actually, Buddhist deities are not supposed to have gender. It's just that Guanyin is often depicted with female characteristics.
