易医玄经（一）异人授易

昔日紫极游历南岳，观赏虫文鸟迹，足迹踏遍禹城三日。心中萌生疑惑，便取钱财掷之。掷时通宝金币落入谷底，被祝融帝收藏，无奈而叹。呆若木鸡，不知所措。

正当此际，禹王前行的人群站立于景前，一人目视紫极良久，说：“君亦通晓易学吗？”紫极答道：“略知其一二。”禹王又问：“能否与吾详述？”紫极回答：“我浅陋的理解尚且不足以言吉凶。”

接着，禹王再问：“为何你显得如此呆滞？”紫極解释说：“有一象必有一事，我不知将要发生的事，你问的是什么？难道也是因为你是易师吗？”禦皇笑着回答：“确实如此，当即提出要传授易学，现在有缘相遇，我便来询问：识得三易八宫之法吗？”

紫極听后深感自卑，但也知道遇到了高人，便恭敬地拜师礼毕，说愿意学习其法则。于是，他向老师请教：

“三易指的是天、地、人的三个层面，其中天者干，用以度量天气；地者支，用以度量土地；人者音，用以度量人的情绪和行为。如果人们在这个世界上，就必须考虑到这三个方面的变化，以便更好地适应周围环境。这就是古代的黄帝五行思想，即干支律音，每个方面都互相制约，从而达到平衡。”

接着，紫極进一步探讨：

“世间关于纳甲纳子纳音的说法早已存在，但您提出的理论更为全面。我想了解其中的奥秘。”老师微笑着回应说，“纳甲之法，如同子午流注最为明了，而纳音之法，如同灵龟飞腾最为广泛。但遗憾的是，只有少数精通医药与易学的人能够掌握这一奥秘。此外，还有其他未曾被发现或未被人们理解的情理，这里不做细究。”

最后，老师告诫他，要将这些知识应用到医疗领域，将会带来巨大的益处，并且能够修福于未来，为百姓带来利益。他还告诉他，只要保持对这门艺术的热爱，就一定能够断开一切困难，让自己成为一个懂得如何趋吉避凶的人。

Purple Extreme asked for the Eight Palaces, and his teacher replied:

"The Eight Palaces refer to the Inner Palace, Outer Palace, Original Palace, Transforming Palace, Flying Palace, Concealing Palace. Among these six palaces are yin and yang energies."

Purple Extreme was confused by this explanation and asked why only six palaces were mentioned. His teacher smiled and explained that the Six Palaces contain Yin and Yang energies within them.

Finally, Purple Extreme asked about the principles of Yin and Yang in medicine. His teacher explained:

"Yin-Yang is a principle of balance. In medicine it refers to eight principles (Ba Jia Yi). The outer palace represents emptiness or absence; the inner palace represents fullness or presence; the original palace represents body or essence; flying palace represents usage or application; concealing palace represents hiding or containment."

After hearing this explanation from his master physician-teachers who had spent their lives studying medical arts combined with Chinese philosophy such as Yijing (Book of Changes), he was deeply grateful for their wisdom imparted upon him through years of apprenticeship under their tutelage.

In conclusion,

The Master said: "You have been blessed with my teaching today but remember that true mastery comes not just from knowledge but also from dedication & practice."
