IMPORTANT SOCIAL MEDIA MEDITATION PRACTICE:
Don't respond to anyone's comment, no matter how belligerent they are, no matter how "right" you are, until you first stop and generate a strong feeling of love and compassion in your heart, towards them. Even if you don't know them at all.
Only once you do, then respond to their comment, speaking to them from that tangible sense of warmth and affinity within.
And watch what happens.
Been doing this for two months now. Gamechanger. Let me know how you go.
Oh, and what if you can't generate such a state of love and resonance towards them? That's easy - then don't comment at all. :)
