During the season of Spring, the Wood energy arises. Wood is associated with movement & is emerging Yang energy (Yang within Yin). It is a transition from a season of Yin to a season of Yang: death to growth & cold to warmth. Similar to how new growth begins to push through the frozen Earth in Spring, Wood energy is expansive, associated with growth & development. In the human body, wood energy is the movement of your muscles & the activity of your tissues. Spring is reminding us of new growth, to let go of the past. Wood energy demands free expression & space for expansion, imbalances gives rise to feelings of resentment, anger, & jealousy regulated within the Liver & Gallbladder meridians.
