If you want to understand suffering you must look into the situation at hand. The teachings say that wherever a problem arises it must be settled right there. Where suffering lies is right where non-suffering will arise, it ceases at the place where it arises. If suffering arises you must contemplate right there, you don't have to run away. You should settle the issue right there. One who runs away from suffering out of fear is the most foolish person of all. He will simply increases his stupidity endlessly.
If you listen to the Dhamma teachings but don't practice you're like a ladle in a soup pot. The ladle is in the soup pot every day, but it doesn't know the taste of the soup. You must reflect and meditate.
The ultimate truth is like the flavour of an apple which you can't see with the eye or hear with the ear. The only way to experience it is to put the teachings into practice. Once you taste it, you are no longer in any doubt about its flavour and you do not have to ask anyone else. The problem is solved.
