Excerpts from Supreme Master Ching Hai’s lecture:
We humans look alike with some very basic instinct, but we develop differently even though we are all Buddhas, and we have Buddha nature. There's nothing but Buddha inside you and around you.
Just like a cup put into the river--it just isolates some water in the river. That's all. As soon as the cup is removed or broken, it's the same like before. It has never been anything different than that. So now, the initiates are like the ones who make a hole in the cup. You know what I mean? So even though we still look like we have a cup, we are inside the cup but we have a hole. Both holes, so the water can come in and out of us all the time. So even though we are concentrated in the cup, we are connected with the whole river; and we are actually the river water now.
