In my experience, meditation is one of the most scientific and tested paths of expanding your consciousness and unleashing the wisdom you have been carrying across lifetimes. And as that happens, you find yourself shedding your baggage, conditioning, guilt and self-doubt. Feelings of resentment and inadequacy give way to tides of bliss and fulfillment. A calm and focused mind is perhaps the most potent weapon to annihilate any obstacle.
