What do you think about the subject?
i just started a course about shamanism on Udemy & feel it holds a lot of promise.
Shamanism and shamanic traveling I can't speak on. I know zilch on it, despite reading a few books back in the 90s for an anthropology of religion class.
Connecting with the earth, do what Im doing, sit outside against trees, greet them before sitting and thank them afterwards, go find collect and inquire about stones. Get into herbs like bulk herbs from coops, and make your own oils and incense.
Take basic science courses on chemistry, biochemistry, biology, botany, geology, zoology, anthropology, earth science, geography.
Go on extensive field trips and get good equipment to take with you like testing kits, microscope, sound recorder, hertz counter and other tools, metal detector, camcorder/digital camera, night goggles, mining tools. Reflective tent, light ballasts, soil, water, miracle for and seeds.
Get earth type statues in your dwelling like a garden gnome for example. Leave out cookies for them in case they drop by, shortbread/sandwich cookies are best.
Get a basic chemistry lab kit and botany and bilogy lab kits, and do basic experiments. Think of impacts on light and color associated with a given topic.
