When Geshe Kelsang taught, all those in the room felt loved. This was because he was looking around the room in a genuine way wanting to see the people not blotting them out. When he saw the people his eyes sparkled he was so delighted. And you could hear the enthusiasm in his voice.
If we are not looking at the people and engaging with them they will not engage with us as well. How can we see a spiritual teacher as a supreme spiritual friend if they act like a stranger and there is no warmth?
There was also no sense that you have to convert to Buddhism or that you are being blotted out because you dont need love or you have not been doing pleasing things. All were loved without exception.
