"The Japanese Zen master Kozan Ichikyo wrote the [above dead] poem in the year 1360 before he laid down his calligraphy brush and left the world while sitting upright... We not only come into this world and leave this world alone, we also cannot take anything along with us into the other world — in case there is one. If there is no permanence, it is also nonsense to tie our boat to our possessions and dreams. Consequently, it is also senseless to cling to certain philosophies, thoughts, feelings, and values, which we take along to the grave when all is said and done. But instead of taking them to the grave with us, it is possible to already learn to let go of them during our lifetime. 1 think that this is a task in life!"
