The absolute reference of WCK and Zen is in the nature of Alertness not in time, space, logical thinking, modern scientific thinking pattern, this moves, that technics, or this secret words.
There is where they meet ------- the nature of alertness. that simple, direct, and clear. within the world and in the same time beyond the world.
your heart have fear due to projection to the future. but your nature of alertness is always there.....
Live in this instant means live with the nature of alertness.
and that nature alertness is not that forcing concentration. that forcing concentration makes us tired and drain energy. It is an effortless alertness. This is the prajna paramita. The wonderful wisdom.
Go back to Chi Sau, let go you and me, let go wanting to win, let go the technics, just do it, jut listern to others and yourself and everything..... just listern and everything will be heard.
There, the nature of alertness will reveal. There, the wisdom of knowing what to do will reveal. There beyond the mind will be understood. There level 3 will be attained.
And this practice is ZaZen in a dynamic way.
There is no need to have secret in WCK. There only if one can attain this nature alertness, the mother of all creation. The original face, the Prajna wisdom, the instantaneous responsor, the core of all.
