What a job it is to be honest. Fear of saying something really shows the fear that you are afraid that someone will see your own faults. In doing something or giving advice you should make sure that you yourself have followed that advice and anything else is just bullshit. When you are completely honest with yourself then what is there to fear? Who can say anything or do anything that can effect you in the least.
To do Zazen is to study the self. To study the self is to come face to face with our little comforts and habits that we just don't want to let go of. Any idea if held to too strongly just creates more dillusion or suffering. I have been afraid at times around certain people because I was afraid that they would see me for truly what I am. No comment or remark can effect you in the least. It is the attachment to some idea that we are holding too strongly. After the honesty and the bullshit, what is there?
After the niceties and frilly carmel coating?
