Chenrezig, also known as Avalokiteshvara, the Buddha of Compassion, is the essence of the compassion of all the Buddhas. With the infinite compassion for all sentient beings, Chenrezig is one of the most popular deities of daily practice. Compassion is a cornerstone of Buddhism. For Mahayana Buddhists, its is an essential quality that must be developed to attain enlightenment. White in color, Four-Armed Chenrezig is the most common form of this Buddha. One pair of hands, folded in prayer, holds a wish-fulfilling jewel, which symbolizes bodhicitta-the altruistic intention. In his second pair of hands, Chenrezig holds a crystal rosary, signifying his ability to liberate sentient beings from cyclic existence, and a blue utpala flower, further demonstrating his pure bodhicitta intention. The deer skin on Chenrezigs left shoulder is a symbol of his gentle nature as well as his skill in taming delusions. By reciting Chenrezigs six-syllable mantra, practitioners develop their capacity to further open their hearts. It is also said that the six syllables correlate to the Six Perfections of generosity, ethics, patience, joyous effort, concentration and wisdom. The mantra for Chenrezig, perhaps the most recited mantra in Tibetan Buddhism, is Om Mani Pamdme Hum.
