How do you comfort those who are sad?

Is not being sad simply a matter of having a question?  Having an unanswered aspect of our lives?  Do not tears represent our longing for filling in the dark unenlightened spaces of our existence?

I comfort those who are sad by helping to inspire their insight to answer their most pressing questions about why people get hurt or die, why our loved ones sometimes seek comfort in the hearts and beds of someone other than their own partners, where the opportunity lays in being let go from a job, why a fascist corporate dictatorship is inevitable on some level, how the most powerful singular person on Earth could actually be the most peaceful one, etc.

It seems to me to all come down to unanswered questions and by assisting people to "fill in the blank areas" that we are able to focus upon that which is truly important and of greater priority in our lives to achieve optimal fulfillment.
