WIY- trying to aqcuire another way to make money for skydiving? (hows that for stalking?)
L613- I am not fluent enough in my torah knowledge but forty is definitely a significant number. Moshe went up to pray for b”y for forty days and was answered by H”m hence setting a precedent for generations. (I leave the rest for more scholarly individuals to expand on including meraglim, ninveh, eliyahu…) Also, you can call up rebetzin teller (rabbi Henoch teller’s wife) and ask her for more info-i know she has done forty days at kosel more than once and may be able to give you more info (without a forty dollar fee)
