Today's hexagram:Water and fire are both harmonious（䷾）

The Book of ChangesThesixty-threeThe hexagram states that when there is an upper barrier (water) and a lower barrier (fire), water and fire intersect, and success is achieved.

Hexagram revelation: When water receives fire, it becomes warm but not cold; when fire receives water, it becomes hot but not fierce; when water and fire are in harmony, they each have their own uses. This hexagram depicts the flourishing scene of things developing to perfection and achieving great success. It symbolizes that in life, one has gone through hardships and finally achieved success, harmonizing yin and yang, and achieving success in all things. Success is not the end, but a new starting point. Learn to remain clear headed in times of success and humble in times of fulfillment, in order to make success lasting.

Be prepared for danger in times of peace, be prepared for it, and be prepared for any danger.
