Think about what it takes to build a house. You need a plan, a strong foundation, framework, a roof, plumbing, electric wiring, etc.
When your house is new, it's in great shape. But, through the years, it can get a little beat up. So you need care and maintenance to make sure your house is strong and can support you properly.
Your body is like your house. Most times (not always) it starts off in good working condition. Wounds can heal quickly, it's strong, fearless and capable.
Over the years, it gets beat up a little - physically, emotionally, mentally, spiritually. Fears, limiting perceptions and poor emotional conditioning get programmed. Those experiences, left unattended, create energetic wounds (energy buildup) - like a boulder blocking a river flow.
Eventually these wounds emanate out to your physical body. It may start out small, like a rash, small ache or imbalance - symptoms you can possibly ignore or bypass - but the more the imbalance continues unaddressed, the wounds get larger and the physical symptoms will get louder and louder until they FORCE you to pay attention.
