Could that person’s sour demeanor be pain?  Could their quietness mask desperation?  Humans are quick to judge without knowing what truly lies beneath the mask.  A smile can just as easily mask pain.  Do you know of any human who has not suffered?  What secrets do you keep from others, thinking they wouldn’t understand?  Do you not yet understand there is only One Mind expressing itself through all of you?  At the deepest level there is nothing but understanding that humans who do not recognize the underlying reality of Purity suffer.  May these reminders engender compassion for others as well as for yourself.  You are so very loved, and you are eternally Love in expression.  Remove the mask and simply be your Self, Peace.
