Clarity, Compassion, and Connection are the three most critical qualities for any working Intuitive.
In my Intuitive Awakening seminars, I coach folks on the Connection aspect (reading energy, interpreting sense impressions, etc.) but cultivating the other two aspects is a serious inside job.
Perceptual Clarity is often viewed as a hard won affair, but really doesn’t have to be. We just need to polish the mental mirror and create space in the "hard drive" of both mind and heart. If you can amp up sensory impressions while radically relaxing thought processes (on demand), you are well on your way to enjoying functional Clairvoyance.
If you add the 'here and now' focus to the mix, the sixth sense rises straight to the surface. My professional ethic is to read for the heart-from the heart. In other words, to get to the heart of the matter in a reading I cling tightly to my own inner sense of love and then Compassion (perceptual clarity devoid of judgement) follows naturally. After all, Clarity and Compassion fit together hand in glove.
