It’s the fifteenth of the lunar month, which in the Gelug tradition of Tibetan Buddhism is held to be an auspicious time to petition the Buddha Amitabha (also known as Amitayus).
As Amitabha or “Infinite Light”, he is portrayed as red in color and dressed in the patchwork robes of a monk. As Amitayus, or “Infinite Life”, he is luminous white and adorned as a celestial deity.
Amitabha/Amitayus appears in nearly three hundred sutras in the Chinese Buddhist canon alone, and his practices are popular throughout Asia. He is recommended not only as a long-life deity, but as a guardian to those in need.
