Dogen instructed, 

Zen Master Daie said, “You must practice the Way with the attitude of a person owing a vast debt and being forced to return it despite being penniless. If you have this frame of mind, it is easy to attain the Way.”  

In Faith In Mind, we read; “The supreme Way is not difficult, just refuse to have preferences.”  

Only when you cast aside the mind of discrimination will you be able to accept it immediately. To cast aside discriminating mind is to depart from ego. Do not think that you learn the buddha-dharma for the sake of some reward for practicing the Buddha-Way. Just practice the buddha-dharma for the sake of the buddha-dharma. Even if you study a thousand sutras and ten thousand commentaries on them, or even if you have sat zazen until your cushion is worn out, it is impossible to attain the Way of the buddhas and patriarchs if this attitude is lacking. Just casting body and mind into the buddha-dharma and, practicing along with others without holding onto previous views, you will be in accordance with the Way immediately.
