Day Tibetan Buddhists meditate on Buddha Deities Amitayus and White Tara, who grant good health and long life. In Tibetan Buddhism, Buddhas and Bodhisattvas are symbolic abstractions and aspects of Adi-Buddha - the masculine and feminine, transcendent and immanent, omniscient and omnipotent, primordial and eternal Absolute.
Amitayus is worshiped in a special ceremony for obtaining long life. He is depicted wearing ornaments and a crown and holding the ambrosia vase from which spill the jewels of eternal life. There are "long-life practices," which summon the life-energy from the elements and the universe through the power of meditation and visualization.
