This is a time of creation and growth. When the Wood energy is repressed, one can experience irritation, anger, hatred and rage. When the Wood energy is depleted, there may be lethargy and depression. The next phase of the cycle is the Fire phase. Fire represents Full Yang, or the energetic phase of the cycle.
Summer is the corresponding season.
This is the most expansive time of the year. Activity is at a peak, and contentment and cooperation prevail. When the Fire energy is blocked, it is expressed at heat or tension, especially in the neck, shoulders and head. When Fire energy is deficient, one may be suspicious, paranoid, lose the memory, or experience emotional unrest. Metal Fire is followed by Metal, which is representative of the Fall season.
