Of course, as God Almighty, Yahweh could just kick back and settle right into the Stillness. In fact, God being God, he/she is the Stillness, the Infinite Source at the foundation of all sound, all activity.
It takes Practice.
Immersed in the buzz of contemporary society (which, itself, could be diagnosed as ADHD), most of us have internalized the incessant noise and relentless activity of a social system build on greed, fear, and ignorance. The noise and activity doesn't just exist "out there." It lives on in our bodies, our emotions and, perhaps most of all, in our thoughts. Even at relative rest, our minds are usually abuzz. Lost in our thoughts, we often feel stressed. It is often acted out (and reinforced) through constant movement. Even "at rest", there is liable to be gum chewing, toe tapping, hair twirling, nail-biting, etc.
Thankfully, in this day and age we also have access to an entire world of Spiritual Teachings, and to meditative practices developed through the ages to free us from this vicious cycle of incessant physical and mental activity. I'm grateful to have stumbled across this vast pool of wisdom as a young man. I have maintained a regular meditation practice for decades.
I don't think this particular gateway to mystical experience is all that removed from the actual experience of most, if not all, human beings. Most of us can recall a time when simply sitting (or standing) still, being quiet, and opening to the sights and sounds around us changed the way we had been experiencing life a few minutes before.
There, in those precious moments, you may become of aware of the amazing world of sensation that you are immersed in, the myriad sights and sounds and feelings that emerge with the inhalation and exhalation of each breath. Just pausing, taking the time to be Present, you can get of your head and into your heart. Your next breath could actually take you all the way hOMe to your True Nature.
