Buddha & Ashoka
Dharma represents the teachings of Gautama Buddha. In some strands of Buddhism it also means existence and the law of being. The Light of Asia is a beautifully poetic introduction to Gautama's life and teachings.
The laws of Karma in Buddhist thought run along the lines of us each being architects of our own fate. It translates into English as 'action' or 'doing'. Our actions in life, in accordance with Dharma, cause us to have a more or less fortunate life on our next cycle as part of Samsara.
