Photograph from the remarkable Buddhist art collection at the Buddha Tooth Relic Temple, Singapore. See the larger version at Water Moon.

अवलोकितेश्वर, also known as Avalokitasvara, is the Bodhisattva of Compassion, and is portrayed as either male or female in different cultures. Guanyin is one of the female depictions of Avalokitasvara as is Cintāmaṇicakra (see Post 1) is one of the male ones.

This posture is called the Water Moon, seated with the right knee raised and the left leg crossed before the body.

This is a 21st century sculpture by Chen Shao Kuan, more of his work at work at Fuguei.com/shao-kuan-chen_artwork
