Don't ever think for a second that you need to meditate 4-12 hours a day to become enlightened, even 2min a day you can become enlightened, most people meditate not to become enlightened but to eradicate pain, negativity, sadness, hurt, anger etc you do not need to "learn" it either, by going away to a temple or guru it is simply sitting quietly observing ones thoughts trying to maintain a calm mind, I use power words in my meditation and a tiny bit of visualization when I can muster it up hehe
