Silence solves the tough questions in life ... IMHO,
How about, sir or madam, may I use these jaws of life to extricate you from your car before it blows up due to the gas leak and fire near your trunk?
Just askin.
Tough questions in life for me are:
1) Who am "I"
2) Why am "I" here
3) Where do "I" come from
4) Where am "I" going after "I" die
At least I know I am not this body, so to me it is not about "having the body extricate from the car before they (body and car) blow up to peaces"
That is not a question, it's 99% sure that the body blows up to peaces (unless the Divine intervenes or some other miracle happens)
Therefore it is important to solve above questions before you step in that car that is going to explode
Silence in this context stands for devotion, concentration, contemplation, meditation, "Being the Witness", introspection and other keys given by the Saints to practice to solve the above "tough questions" in life.
