So what is this Wood energy doing? 

It is moving forward, a direct assertive energy making no apologies for pushing things out of its way.

The Five Elements in Nature
Spring is also the time of hope; this season bursts forward with optimism, offering change after the quiet, still time of Winter.

Each seed and sapling is following its own part of nature's plan. Think of the wood of a tree, it gives nature structure and shape but does not let anything hold it back as it drives forward. 

Without this type of change all things would wither and die.
As in nature the Wood energy is part of the energy of our body - the acupuncture meridians of the Liver and Gall Bladder.

Given that each meridian has a job in the body s kingdom, the Gall Bladder meridian is "The Upright Official who Excels in Judgment" and the Liver is "The Official in Charge of Planning".
These Wood meridians give us the energy...

to have new ideas
to move forward,
to have plans
to change who we are,
to be assertive,
to make decisions,
to have vision,
to have hope for our future. 
Spring and Wood
Spring is the beginning of the season cycle, a time of birth and new beginnings. It is also the energy of the element Wood. 

This is the energy that brings forth new growth, that pushes the new grass through the snow, the new branches out from old wood, produces new leaves. It does this so nature can take in the nourishment it needs to flourish.
