The Power of Tears:
The gates of tears never close. The power of davening with tears is indescribable and can bring about great salvations.
A story is related about a young man who didn't have children for many years. He approached Rav Shimshon Pinkus zt"l, the Rov of Ofakim, and cried about his dire situation. Rav Pinkus told him, "Come back at 2 am and I will try to help you."
The man returned at that time, and Rav Pinkus told him to get into his car. He drove him out of the city, to a remote, desolate place. He told him to get out of the car and said, "You are now alone in the desert. It is just you and Hashem. Cry to Him. Speak to Him like a person speaks to his friend and beg Him for salvation. I will be back in half an hour to take you home."
When Rav Pinkus returned half an hour later, he looked at the man and said, "You didn't cry enough. You need to cry for real! You need to cry out from the depths of your soul."
He came back after another half hour. This time, he saw that the young man's face and shirt were drenched with tears. He smiled and said, “That is what I intended. Now you will see your salvation."
And so it was.
