I read this a few days ago and it stuck with me.
When my master and I were walking in the rain, he would say, "Do not walk so fast, the rain is everywhere. - S. Suzuki
That's a Zen state of mind. So the rain could be considered life, and all the hardship it throws at us.
The Zen master said, don't walk so fast. Meaning, don't react, take it easy, breathe, and mindfully respond. The ego reacts, consciousness or the higher self responds. There is depth in responding. To respond, one must be present, and grounded.
The rain is everywhere. Indeed it is, and it wont stop, it'll keep coming. That said, we meditate, decondition ourselves, and become better at living life. We master it rather than fall into its silly traps.
In Zen, we practice Zazen, which is Zen meditation. After practicing Zazen for some time, we learn how transcend life's constructs and traps, and Zen becomes a way of life.
