I begin to understand as to why the first time, I read Dao De Jing (DDJ), and I try to understand. Second time, I tried to remember, Third time, I got lost and confused and Fourth time, I forgotten everything. This very passage, 道可道,非常道, the expressed Dao is not the true Dao, is what it meant. With such, I was reminded again by Heavenly will to stay away for 名可名,非常名.
Only, the who seeks will not find, the one who found, will not seek. This I remembered.
