OK, here goes ... this is why I think so many people enjoy zentangles.
The human body is made up of two parts - the physical copy and the energy copy. The energy copy is what keeps us alive, without it, there is just a body. Another word for this energy is vibration. We are all a unique vibration.
Everything has its own vibration. In homeopathy, we call this the "vital force." Homeopathy is also known as energy medicine or vibrational medicine. The remedy (the medicine) is actually the energy or vibration of whatever substance is used to create it. This can be a mineral, plant, or animal or human milk.
Nikola Tesla was an inventor, engineer, and physicist in the mid-1800s to 1900s. He invented a "vibration board." He discovered certain vibrations could cause physical symptoms in the body. His good friend Mark Twain also discovered this one day when playing on the board he suddenly developed diarrhea! What Tesla didn't know (or perhaps he did) was that he was demonstrating how homeopathic remedies work.
Like the vibration board, the vibration of each substance (mineral, plant, or milk) can and does cause physical symptoms. Homeopathy means, "like cures like." So if you already have those symptoms and you take the energy of those symptoms there is a physical reaction - laws of physics - for every action there is an equal and opposite reaction. In this case, the body throws off the symptoms in the equal reaction which results in cure. But our energy/vibration must match the vibration of the remedy or nothing happens.
Well, each vibration makes a pattern. (See this video or search vibration pattern table on youtube:
The Art of Sound Sound is a vibration. So you can see, each sound/frequency/vibration makes a distinct pattern. I believe we naturally resonate with certain patterns of Zentangle because of our own energy. And in some ways, we are actually self-medicating by drawing those patterns over and over in a creative manner.
Sorry this is so out there! But this is what I do in the other portion of my life not dedicated to calligraphy!
