[Avodah] Mahal and Giglgulim

[Joel C. Salomon]

This past Shabbos, our Rav mentioned a story about the Maharal of Prague
involving gilgulim.  (I've also found this story online at
<http://www.eflip.com/prozdor/B_SHM67/p070302.pdf>.)  Given what little
I've read of the Maharal's concept of kabbalah (mostly in the context of
"no, he never made a golem") this felt a bit surprising to me, so I
thought I'd ask those with greater knowledge of the topic:

What is known about the Maharal's attitude toward the concept of gigulim?
