So it is essential to bring more consciousness into your life in ordinary situations when everything is going relatively smoothly. In this way, you grow in presence power. It generates an energy field in you and around you of a high vibrational frequency. No unconsciousness , no negativity, no discord or violence can enter that field and survive, just as darkness cannot survive in the presence of light.
