【Aruṇa】Also written Aruṇa, or called Sattva; in Chinese it means the "sign of dawn". The Mingliao lun states: "The east has already reddened." Tonghui's Zhigui states: "In this land, approximately two ke before sunrise is daybreak; this is the sign of dawn. Using the ability to clearly distinguish the lines on one's palm as the limit is the dawn according to the Dharmaguptaka-vinaya. Another school calls it the time when the ground is discernible, meaning the color of the earth can be clearly distinguished." It also says: The rising sun reflecting upon the color of the jambu tree is called the sign of dawn. The Ākāśagarbha-sūtra states: "When this beginner bodhisattva sees the morning star appear, he rises from his seat, faces the morning star, and speaks these words: 'Homage to Aruṇa! Perfected in great compassion, now newly appearing over Jambudvīpa, may you protect me with great compassion. I speak to the Great Compassionate Bodhisattva Ākāśagarbha, that he may manifest expedient means to me in my night dreams, so that by this cause I may repent of the fundamental grave offenses I have committed.'"
