I quote from what is claimed to be the oldest school of Qigong, ZYQ, Zhong Yuan Qigong:
"The first step of the transformation of Jing into Qi involves bringing it up to the brain. This can result in our acquisition of special (extrasensory) abilities, prolongation of youth, and achievement of longevity."
I have personally verified the above description when instructed in the Transcendental Meditation Siddhi program. The first time I practiced this advanced method based on the correct understanding of Patanjali's yoga sutras method which had been missing for hundreds of years, energy spontaneously shot up thru my heart chakra and then into the brain resulting in the experience of what TM program calls Cosmic Consciousness, the first stage of enlightenment. This sounds like bringing Jing up to the brain. At the time of this glorious experience, I thought of it as Kundalini rising from the base chakra all the way to the crown chakra. This sounds similar to "bringing it up to the brain". The beauty and blessing of the TM Siddhi program is that it happens effortlessly. Unlike Taoist alchemy Qigong, it does not involve any visualization or concentration at all. Kudos to the ancient Taoists, but their strenuous and lengthy, lifelong practices that only a few people ever succeed in doing, are not needed when TM programs allow people to reach the goal of Taoist alchemy immediately and without strenuous, laborious, hit and miss methods with a very low success rate. If one has the right karma, the right master appears. Otherwise, years of wasted, fruitless effort, all in vain.
