I went to some of his shiurim in Yerushalayim.
He had a fantastic koach of taking lofty ideas, and explaining them in laymans terms, using good meshalim.
Also I found with him, he used stories of himself to create lessons.
I recently saw somewhere, a man came to him to ask him to daven on his behalf that he should be zoiche to have children. Rav Shimshon said “I cant help you now. Come back at 2am”
Well, if that what it takes, thats what he did. At 2am he knocks on the door. Rav shimshon said “come, lets go for a ride”.
Off they went, in the car, along the road leading out of the city. They come to the dessert, and they drive for a few minutes. Rav Shimshon stops the car and gets out.
He turns to the guy and says “stay here for a half hour, daven, scream to Hashem from the bottom of your heart. Tell him how much you want this. You are in a dessert so noone will be disturbed, no-one will hear. I will be back in 30 minutes to fetch you”.
30 Minutes later rav Shimshon returns, and says to the guy “No. You havent done what I said. I want you to really pour your heart out. But really let it all out. I will be back in half an hour”
Half an hour later he returns, and the guys shirt is wet from tears and sweat. His face is stained from tears. Rav Shimshon says “ah. I can see you did as instructed. Now we can go home”
Within the year the couple had a baby.
Rav Shimshon explained, that a serious pure tefilla from the depths of the heart never goes unanswered. Is better than any B’racha. – BUT IT MUST BE 100%!
He was a “no frills” emesdike tzaddik!
