All of these deities, all of these enlightened beings that we are visualizing in front of us in the sky, are not just there in empty space, but are there in the pure land of Green Tara. That pure land is called Yulod Kurpa, which means "the Turquoise-colored Pureland". This is her heavenly, or celestial, paradise, which is complete with all aspects of a diving paradise, and is characterized by this turquoise color. This entire assembly arises here in this green pure land. This is the name of Her celestial paradise, where living beings go to attain enlightenment. Something should be said about this turquoise-colored paradise. It resembles some sort of fantastic heavenly rock 'n roll party. The deities there are filled with bliss, spending their time in dance and song, special enlightened dance and song, so that if ordinary beings even perceive it, even see it, they are filled with a sense of happiness and faith.
