There are different types of medicine bags and all are wise to create.
The one I am going to describe to you today is a protection of sorts. It doesn’t matter if you are Catholic or Buddhist, I think we all understand that there is a lot out there that we do not fully grasp. We are a small part of the whole. Regardless of the believer’s perceived notions on heaven and hell, there is no doubt that there are spirits, some good, some evil, entities of destruction and angels of good. We can help in the protection of our own being. You might see some people have a Native medicine bag attached to their belt or used as a purse but those are for show. A real medicine bag must be hidden. Worn under the clothes or kept very close in a purse or the like, a medicine bag is a protection device.
My first teacher, a wise shaman, taught me to fill mine with something from every element and helper. I used rocks, and feathers, and totems, and herbs, and boy was it heavy! One could simply use sage, cedar, sweet grass, tobacco, rocks or totems of meaning, feathers, medals, or holy soil. Listen to yourself find the perfect combination. One doesn’t divulge what is in their own personal medicine bag. Having a shaman smudge it makes it stronger and secure. (If you don’t know one, do it yourself with cedar and sage.)
For those that are healers, intuitives, and empaths, these are imperative as good work is often trifled with from the dark side, but even those that do not find themselves in these descriptions can benefit from extra protection from the negative forces of this world. Be safe out there and do good works!
