During zazen, brain and consciousness become pure. It's exactly like muddy water left to stand in a glass. Little by little, the sediment sinks to the bottom and the water becomes pure.
Taisen DeshimaruZen is not a particular state but the normal state: silent, peaceful, unagitated. In Zazen neither intention, analysis, specific effort nor imagination take place. It's enough just to be without hypocrisy, dogmatism, arrogance - embracing all opposites.
Taisen DeshimaruNobody today is normal, everybody is a little bit crazy or unbalanced, people's minds are running all the time. Their perceptions of the world are partial, incomplete. They are eaten alive by their egos. They think they see, but they are mistaken; all they do is project their madness, their world, upon the world. There is no clarity, no wisdom in that!
