Slowly or not at all could be indicators of low psychic energy. Whether we are doing shamanic healing for others or the planet, or if we simply want our own lives to run more smoothly, increasing our psychic energy can fuel the visions. Opportunities for increasing energy are all around us. We only need to recognize them. Like learning where the local markets, restaurants and gas stations are, once you know, it's easy to get there.
Nature is filled with abundant energy sources.
Streams, hilltops, sunshine, waterfalls, caves, forests, gardens, and animals just to name a few. Sometimes the sheer intensity of energy around you can increase your field of energy. Sometimes its peacefulness can relax you, which has the effect of freeing up blocked energy. These journeys can have powerful effects, especially if we notice the energy fields while we're there. There are many places within a city to experience high energy fields.
