The Bodhisattva of wisdom. He was born holding in his right hand the flaming sword of wisdom, and in his left hand a blue lotus blossom, and supporting the book of (the perfection of) wisdom.
Also, another one of my nicknames. This one is one of the best because the Dalai Lama gave it to me.
He is usually represented as follows "In his right hand, raised above his head, he wields the symbol most distinctively his, a flaming sword of wisdom that cuts through the ignorance which binds sentient beings to a cycle of suffering and unhappiness. In his left hand, at his heart, he holds a book, a volume of the Perfection of Wisdom, representing both the source and embodiment of his awakened understanding."
