There are many ways of running ground energy. The Chinese and Indian Yogi's have explored them and while that is very interesting, the practical improvement for many is marginal. People are attracted to these because they have an element that is foreign, they are exotic. Many would benefit but few are able to utilize them. If you do not have training in these systems from past lives, they are difficult to learn. We are beings of duality; everything in this reality is dualistic.  While in the womb, we are connected to our mother, physically and energetically.  When we are born, we disconnect from our mother and are only one half of what we want to be.  So before we are born we feel complete, while at birth we feel incomplete.  As we breathe and experience the lightness of air, we automatically dive with the enrgy of the Shushumna, our central column of energy, down to the dualistic opposite, the density of the center of the earth.  We typically stop prior to reaching the center at a dense layer of rock or compacted gravel.  This becomes our home strata.  This is how we develop our initial grounding, which provides us with both access to the fundamental energy of the earth and a surety of safety and security.  This all takes place in the first few independent breaths. Due to the artificiality of our civilization, which we do not fully comprehend due to our immersion, Simpler mundane practices are very important. Sensitivity to the earth beneath the feet can be developed by removing the artificial barriers from the feet to the earth such as shoes. This along with conscious diaphragm breathing allows your experience to develop. Initially the experience is under or beneath consciousness; with practice, consciousness may be extended to these very low frequencies. Then you will be able to understand to some degree the experience of the North American Indians, Australian Aboriginals, and other indigineous people whose consciousness has included experiencing the earth and its energy since birth.
