Feng shui principles acknowledge the correct cycle of the five elements and teaches you how to apply them in your home and life for a balanced life so chi energy can thrive.
First - This is the creative creative cycle and is the ideal because it produces the next element in the circle of creation.
Second - This controlling cycle also becomes destructive.
Third - The third cycle weakens the elements so the chi energy no longer nourishes but weakens the other elements.
