The I-Ching, also known as "Book of Changes", is an ancient Chinese oracle(divination) text that is thought to be the oldest book still in existence today, with a history of more than two and a half millennia of commentary and interpretation alone.

The I-Ching is a means of obtaining spiritual guidance, inspirational insight, and Universal wisdom. The philosophy of I-Ching is focused on the universal principle of change. Change is eternal and universal, both in a cosmic and humanistic sense.

The I-Ching teaches that it is necessary to learn how to appreciate the philosophy of change and to know how to adapt to it.

The book offers a wealth of beautiful poetry and Chinese philosophy that goes back to the origins of ancient Chinese customs and values.
