It's important to bear in mind that meditation is a religious practice specifically aimed at causing ego-death. Yogis writing about the practice (before it became big business) freely admit all sorts of horrible-sounding mental side effects, but couch them in religious terms (and encourage the acolyte to push through until they achieve "enlightenment", which they describe as a profoundly nihilist state of being). This whole idea of it being a casual activity that's good for the soul, or that it can make you a more effective person (on this plane of existence) is 1) new and 2) only modestly supported by the science.
It may hold some value, but it strikes me that there is more pro-meditation dogma than anti-. Scientists will hold an open mind, but "gurus" who charge money for fancy retreats will insist in its value without evidence. As a general rule, there are no panaceas - major changes in cognition can go either way. Be careful!
