The gap between who you are and who you say (pretend) you are causes stress. Most of us have lofty ideals and mediocre (at best) actions…
This is why noted gurus, healers, coaches, teachers have a low vibration.
You, the person seeking enlightenment, peace, healing, or success, expect the person who teaches you to know it all, be all, and never have any negative feelings, to not be like you.
The truth is that no matter where you are on the evolutionary scale, you will always have negative feelings.
The difference between someone with low vibration and someone with high vibration is what they do with the negative feelings.
