A really nice metaphor in Sharon Salzberg's Lovingkindness (on p. 53-4 of my copy):
Imagine taking a very small glass of water and putting into it a teaspoon of salt. Because of the small size of the container, the teaspoon of salt is going to have a big impact upon the water. However, if you approach a much larger body of water, such as a lake, and put into it that same teaspoonful of salt, it will not have the same intensity of impact, because of the vastness and openness of the vessel receiving it. Even when the salt remains the same, the spaciousness of the vessel receiving it changes everything.
We spend a lot of our lives looking for a feeling of safety or protection; we try to alter the amount of salt that comes our way. Ironically, the salt is the very thing that we cannot do anything about, as life changes and offers us repeated ups and downs. Our true work is to create a container so immense that any amount of salt, even a truckload, can come into it without affecting our capacity to receive it. No situation, even an extreme one, then can mandate a particular reaction.
