Everything in this world is relative because there are no clear boundaries between big and small, soft and hard, good and bad, etc. Even a large thing is small in comparison with the largest one, and even a soft thing is hard compared to the softest one. A good deed can be bad in a broader context, and a bad action can be perceived as good in a new dimension. Failure can create luck, and luck can open the way to subsequent failure. Your joy is not eternal, nor is your sorrow. Everything changes, everything turns into its opposite. Winnings carry out losses, and losses contain winnings. Rejoice, knowing that you will grieve, and grieve, knowing that you will rejoice.
