I think the topic of energy is fascinating. I'm amazed at how energy is always being exchanged and converted through billions of interactions around us every day. I'm the furthest thing from a scientist, but I do recall learning about kinetic and potential, or stored, energy. These can include chemical, electrical, magnetic, radiant, thermal, mechanical, nuclear, and other energy forms. I also remember learning the first law of thermodynamics which states that energy can not be created or destroyed, but it can be changed from one form to another.
It's easy to see large scale energy interactions like water freezing or being converted to steam, but some people fail to acknowledge the finer energy interactions in our lives that are not always visible to the naked eye. Everything we do involves energy interactions. This includes our thoughts, the words we speak, the music we listen to, media we watch, and the food we eat.
I used to be much more closed minded about body energy and dismissed it as a touchy-feely topic but, as I have aged, I have become more sensitive to that kind of energy. Whether or not you believe in chakras, meridians, auras, etc., it is hard to deny that we are always absorbing or giving off vibrations to or from our environment and others. Have you ever come across someone you just didn't seem to click with because you felt they gave off "bad vibes"? Have you been attracted to others easily due to their pleasant personalities?
The environments we submerge ourselves in can produce either positive or negative energy interactions. Examples of positive exchanges of energy include thinking pleasant thoughts or recalling good memories, giving and receiving kind greetings or compliments, enjoying music you like, a hug, or a massage. Negative energy exchanges include things like getting a sunburn, incurring injuries, dealing with criticism and contention, verbal assaults, or experiencing physical trauma.
