As the people are reincarnated, they purify their Kias and give them the chance to learn. A mage whose Kia has undergone many Good Deaths will have a most powerful inner core. The Wheel might slow down or even stop for a time, but it will continue its unending cycles. There is only one true source of wisdom, and that is your intuition. It is the whispered wisdom of your past incarnations, the amassed learning of your Kia.
New possibilities enter the world constantly.
In some places they grow stronger than others, forming gardens of possibilities and newness. A wise mage gathers the growth, and prunes the weeds of these gardens.
