The Karma Oracle by Laura Tuan is based on the principles of Vedic and Hindu cosmology.  The cards are divided into four groups.  The first twelve (blue background) show the gods and goddesses who represent certain universal laws.  The next ten cards (yellow background) show the mythic animals ridden by the gods.  These represent areas of life such as work, love and health.  The next eight cards (red background) show objects used by the gods.  These are the actions and behaviors we need to help release karmic knots.  The last three cards are the three pillars of Indian philosophy: karma, dharma and moksha.  The instruciton booklet explains the symbolism of the cards and how to use them to explore a previous life and current specific situation.
