Everything has a spirit everything has their own energy from the smallest of ant, to the big elephant to the killer whale. From the trees to the rock to the water that you drink it all has it energy and it all has it magic and lessons that it wishes to teach you. This is just a basic view of tree magic from personal experience.
What is tree magic? Almost every native culture has some belief about tree magic theCeltic Druids seen them as a source of healing and blessings, Aboriginal Australia worked with the leaves of the trees to help them with sore throats and other sickness or is seen as a blessing from which fruit would grow from and a source of food in other cultures. Even today in some practice oils and herbs are being put to work to help add the energy in spells that witches create.
Wands: making our own wand is a form of tree magic since it had came from a tree or have fallen off. There is a reason why you must never take a branch off a tree and use it as a wand without its permission if placed in a room it can be sent as nightmares to a person.
Anxious/ depression: herbs, oils and incense are a great form of brining healing to those who battle anxious and depression it brings a sense of peace and connection it also helps ground the person and brings a sense of strength. (If you go through any mental illness please remember to speak to medical professionals or close family and friends.)
Ground: if your a person whom has trouble grounding themselves then trees are a great way to help teach you to ground. By simply being near the tree or leaning your back against it with the intention to ground you won't end up feeling out of body. You could also picture being next to a tree during meditation to help you ground and come back to Mother Earth.
Mediation excuse: this is something which I had found out earlier on my path it is a working process and a slow build. You can either find a tree in a park or in a garden and go up to it every day and speak or sing to it. You can introduce yourself if you wish to and do this over for several weeks. Find a stick which has dropped on the ground and sit beside that tree during meditation one day. Place the stick into the dirt and close your eyes and let yourself be and listen. You may find something surprising that you hadn't been able to notice before.
During this process you and the tree will form a bond of sorts and friendship you may noticed that your more interesting in either writing and drawing sudden ideas which has a peaceful energy to them. 90 percent of the time you will be channeling information from that tree.
