Is suffering inevitable?

Is it possible to obtain the total knowledge of the universe without withstanding tons of suffering? Yes, that is possible, but what is the probability to achieve all that knowledge without having some kind of problems?

Even if the locksmith which guards the key of the Source of Knowledge can offer it to you, you should show him that you are capable of doing a REALLY good use of it. For example, if you pass through any kind of suffering, you must rip off any feelings of revenge, and move towards a total development and improvement of your life.
