So what if we could be on the wavelength of anybody? I personally am trying to do this myself, trying to judge others less, and accept people. Of course there are people I don't want to be involved in my personal life, and I have made measures to do so. I don't believe this to be hypocritical, there are just people out there who may have a negative influence on you or people who are holding you back from what you believe is your potential. Though, to understand life and this "whole" we need to understand everybody and everything without exception.
In short, it's important to have a wavelength or form of understanding to give compassion and acceptance to all beings. Also it is very important to realize the influence and affect we all have on each other.
