The Buddha said to Subhuti, “In a place where there is something that can be distinguished by signs, in that place there is deception. If you can see the signless nature of signs, then you can see the Tathagatha.”
—Diamond Sutra, section 5
Look deeply at the one you love (or at someone you do not like at all!) and you will see that she is not herself alone. “She” includes her education, society, culture, heredity, parents, and all the things that contribute to her being. When we see that, we truly understand her. If she makes us unhappy, we can see that did not intend to but that unfavorable conditions made her do it. To protect and cultivate the good qualities in her, we need to know how to protect and cultivate the elements outside of her, including ourselves that make her fresh and lovely. If we are peaceful and pleasant, she too will be peaceful and pleasant.
If we look deeply into A and see that A is not A, we see A in its fullest flowering. At that time love becomes true love, generosity becomes true generosity, practicing the precepts becomes truly practicing the precepts, and support becomes true support. This is the way the Buddha looks at a rose, and it is why he is not attached to the rose. When we are still caught in signs, we are still attached to the rose. A Chinese Zen master once said, “Before practicing Zen, mountains are mountains and rivers are rivers. While practicing Zen, mountains are no longer mountains and rivers are no longer rivers. After practicing, mountains are mountains again and rivers are rivers again.” These are dialectics of prajnaparamita.
