From Jack Kornfield: If [we] put a spoonful of salt in a cup of water it tastes very salty. If [we] put a spoonful of salt in a lake of fresh water the taste is still pure and clear. Peace comes when our hearts are open like the sky, vast as the ocean.
One way to practice this when we get caught in the waves of one of life's "salty" situations is to be aware of allowing the space around the heart to remain (or return to being) soft and spacious. Another is to ask ourselves the yogic inquiry question: Who is aware of this [sensation, thought, feeling, situation]? and sense into that before responding.
Happy exploring!
