If there are fish that would swim or birds that would fly only after investigating the entire ocean or sky, they would find neither path nor place. - Dōgen

As long as you try to figure out buddha dharma with mind, you can never attain it even for myriad eons or thousands of lifetimes. It is attained by letting go of the mind and abandoning views and interpretations.

To study the Buddha Way is to study the self. To study the self is to forget the self. To forget the self is to be actualized by myriad things. When actualized by myriad things, your body and mind as well as the bodies and minds of others drop away. No trace of enlightenment remains, and this no-trace continues endlessly.

Life and death are of supreme importance. Time swiftly passes by and opportunity is lost. Each of us should strive to awaken. Awaken! Take heed, do not squander your life.
