Word on the street is that kundalini techniques can improve your attitude. If the muggy city heat is making you testy, join a yoga workshop tomorrow: "Manifesting Your Life with Yoga" (3--5pm, $40), at midtown studio Prana Mandir, puts the practice to use for developing a positive outlook and breaking through negative patterns. Chances are you'll get a couple good hours of AC, too.
