Suvarṇadvipi Dharmakīrti Philosopher
Dharmarakṣita, also known as Suvarnadvipi Dharmakīrti (Tibetan: Serlingpa Chökyi Drakpa; Wylie: Gser-gling-pa chos kyi grags pa, Chinese: 金州大師), was a renowned 10th century Sumatran Buddhist teacher who composed an important Mahayana text called the Wheel of Sharp Weapons (Tib. blo-sbyong mtshon-cha 'khor-lo). He was the teacher of Atisha, who was instrumental in establishing a second wave of Buddhism in Tibet. 'Wheel of Sharp Weapons' is an abbreviated title for 'The Wheel of Sharp Weapons Effectively Striking the Heart of the Foe.' This text is often referenced as a detailed source for how the laws of karma play out in our lives; it reveals many specific effects and their causes. A poetic presentation, the "wheel of sharp weapons" can be visualized as something we throw out or propel, which then comes back to cut us... something like a boomerang. In the same way, Dharmarakshita explains, the non-virtuous causes we create through our self-interested behavior come back to 'cut us' in future lives as the ripening of the negative karma such actions create. This, he explains, is the source of all our pain and suffering.
