Reb Zemele, while sitting with his Hasidim, joking said, "When a Jew has finished his prayers, one should greet him with 'Shalom Aleichem'."

"Why?" the Hasidim asked.

"Because I am sure there is not a spot on earth to which he did not wander, while standing in prayer."

Prayer is not easy. It takes desire, focus and concentration.  And patience.
