This is my practice space for sitting meditation tonight. Nothing special. And at the same time the most special place to me - my home. Kids are sleeping. No idea of any gain, I think... And I enjoy it tonight. Sitting still. Sounds from the dishwasher in the kitchen. Folding my legs and relaxing into the posture. Nothing more to accomplish today. Just sitting.
Nishijima Roshi said that the goal of zazen - sitting meditation - is zazen itself. And at the same time he, for example, included the Bodhisattva vows at ordinations. "I vow to save all beings..."
My heart holds shikantaza zazen - just sitting - dearly. But I also call our public sittings "meditation for peace". What is "for peace"? What does it mean to state such a direction, purpose, or dedication for the practice? As I replied to Mike Cross' comment in the post below, my peace is almost always disturbed anyway...
I'm not sure how to best put it in words, but in my limited experience it holds together. Perhaps somehow related to the Christian concepts of law and grace? Right now, I don't know. Just sitting, leaving thoughts of different kinds of worth behind, and it's far from worthless. In this flowing weaving of things, perhaps a sense of being near. A manifestation of peace, even when I'm far from it. It's for all beings.
