Bell Jar - A Symbol of Protection and Safety

Bell jars have long been used to protect delicate items from harm, whether it be a glass jar filled with food or a glass bottle used for scientific experiments. When we cover a glass bottle with a bell jar, we create a safe environment where nothing can harm what is inside. Similarly, when we clear the bell jar after an obstacle is cleared or when we drop the bell jar after a sudden stop, we feel a sense of relief and freedom, just like how we would feel if we had cleared all the obstacles in our lives and were free to breathe again. However, if the cover of the bell jar is loose, it can cause some air to leak out, symbolizing that something is not completely safe or protected. Therefore, we must always be vigilant and take precautions to ensure that we are protected and safe at all times.
