They are not the same, but there are important similarities at some levels.
The overriding similarity concerns awareness. The difference is that zen is concerned with awareness without object and Cui is concerned with awareness directed at the learning of children occuring in the PRESENT MOMENT.
The quality of empathic awareness in the perceiver is paramount to the Cui Way. The early pioneers understood this only too well and gave it a name:
THE SUBORDINATION OF TEACHING TO LEARNING
It is this, combined with the generalised visual implications of rod relationships that sets the Cui Way apart from, indeed worlds away from that certain something which normally occurs in schools.
