He is from Russia and has been living in Israel for 20 years. When I asked him to put on tefillin he declined saying, "I don't know how."
"That's what I'm here for."
He walked over and followed the instructions. As soon as he finished reading the Shema he asked, "Is that it?"
"No, no way! Now the most important part; when you do a mitzvah, when you do what Hashem wants you to do, the gate to Heaven opens. This happens anywhere in the world but even more so here at the Kotel. Take advantage of this. Close your eyes and picture everyone you love one at a time with light on their faces and smiling and ask G-d to bless them. Then ask Him to protect the Jews in danger. Say thank you for all the good He has given you. Picture all the good things you want to bring into the world. Talk to G-d in your heart."
He followed the instructions and stood there for a long time reaching up to Heaven.
This is the part of the mitzvah that touches them the most. Prayer puts us on a spiritual ladder. The more we reach up the higher our prayers go and the better we feel doing it. G-d is everywhere, but He has us reach up to try to bring about the good things that we want to bring into the world.
