I'd have to disagree on that a bit, the magical bit, since you do find stories of those experimenting with ecstatic trances, people sitting with their feet in buckets of ice water, other mystical practices. Dunno if that falls within Kabbalah per se but some kabbalists, like all mystics, took it to that extreme.
While you posted I found a few more quotes to play with. Btw I do find your insight on this really good; most of what I know of kabbalah is from just reading Scholem and from this class.
Gikatilla, Gates of Light
"The Righteous One stands gazing out at humanity. When he sees human beings engaged in Torah and mitzvot... then the Righteous One expands, filling himself with all kinds of flowing emanation from above, to pour into the Shekhinah, in order to reward those purifying themselves (etc.). Thus the entire world is blessed by those righteous humans, and the Shekhinah is likewise blessed through them. But if, God forbid, humans defile themselves... when he sees, he gathers and contracts himself, ascending higher and higher. then the flow of all the channels ceases, and the Shekhinah is left dry and empty, lacking all good. ... Now come and see the power of the righteous: they can unite all the sefirot, harmonizing the upper and the lower worlds."
Kabbalistic Manuscript Tradition
"The head of man corresponds to the Supreme Crown... the brain and the palate fo man correspond to Wisdom... His tongue corresponds to Understanding... The extension of the body corresponds to Beauty... The arms correspond to Love and Power, Love is the right and Power the left. Endurance on the right and majesty on the left. foundation corresponds to the phallus which is set in the middle. This is the form that we have explained... and it corresponds to the human body, for the nine sefirot are portrayed as the anthropos..."
