Just briefly I wanted to address the first question. The reason for this is that I see the question of ecstatic experience and also the dominance of Meshuga miracle workers [mad, insane lunatic charismatic leaders] is troubling.
I really just wanted to make one point --that Torah is not about mystic experience. It is not to come to that type of thing. What is usually see with people getting something like a LSD "high" from reading kabalah or coming to some lunatic meshuga supposed miracle worker is not what Torah is about.
However true attachment with God can be a result of faithful service towards God. As the Torah says ולדבקה בו "keep his commandments in order to love and fear God and to be attached with Him."
