I started my spiritual exploration in a bit more of an esoteric vein. So that is probably where this question comes from.

My interest in Zen increased greatly after reading "Zen Training: Methods and Philosophy" by Katsuki Sekida. In the technique of zazen provided it has one hold their attention and just sit with the seika tanden. Being of like mind to such concepts i didn't question it, and found it to be an amazing tool in my life.

Lo and behold in learning more of shikantaza I was waiting for the video blog where Jundo instructs us to do the same and perhaps discusses it some. SURPISE! I have gone through the first few months worth of this years archives and never came across it.

So now I wonder why? Is this practice more in line with Rinzai teaching?
