Controlling the frequency of your surrounding field can be a useful tool from both a practical and personal growth perspective. The more you grow as an energetic being, the higher the frequency and to some degree it’s under your control through intent. The highest vibration on this plane is love, so it makes sense that the more unconditional love you are able to express, the higher your vibrational frequency. This is a double edged sword. It will attract those that are drawn to this vibration and help them to grow, but also acts as a mirror to those looking into it which can be uncomfortable to anyone not liking themselves. Often this uncomfortable feeling will be blamed on you.
I like keeping my vibrational field as high as I can, the idea being that it will help me to grow and process myself on an ongoing basis. I envision this field spinning around me at as high a frequency I can and intend, but because this may not be appropriate in the company of others I have also intended a dampening shield enclosing it that adjust the frequency as it flows through the shield to become the perfect frequency for each person I come into contact with. I feel this way I can support each person on their journey in the best and highest way.
