When you stand are you balanced in an easy way for your body. How does gravity go through you? These stones on Holy Island (Lindisfarne) are balanced or they would fall over.
How we balance all started when we stood for the first time and took those first steps to start walking. Our head balances on top of the spine like a ping pong ball with the hips knees and ankles in line below. We fell over as small children as we learned how to balance.
This easy effortless way of balancing gets interfered with as we develop unhelpful habits resulting in tension when you stand and move. These habits keep us upright so we do not fall but there is a strain on our bodies. Many people lock their knees back in standing which pushes their hips forward altering the alignment of the spine and how their shoulder girdles sit on top of the ribcage.
Notice how much weight you have through your heels. Many people have a lot of weight through the front of the feet but you need 60% of your weight through your heels. So just notice what your habit is.
Learn to be poised.
