Although the classical descriptions place heavy emphasis on the awakening of kundalini in mooladhara chakra, there is a widespread misconception that kundalini must be awakened there and made to travel through and awaken all the chakras in turn. In fact, the seat of kundalini is actually sahasrara. Mooladhara is only a manipulating center or switch, like the other chakras, but it happens to be easier for most people to operate this switch. Each of the chakras is independent; they are not connected with each other. This means, if kundalini shakti awakens in mooladhara, it goes directly to sahasrara, to a particular center in the brain. Similarly, from swadhisthana the shakti passes directly to sahasrara, from manipura it goes straight to sahasrara and so on. Kundalini can be awakened in an individual chakra or it can awaken throughout the whole network of chakras collectively. From each chakra, the awakening shock moves up to the top of sahasrara. However, the awakening is not sustained and those centers in the brain return to dormancy. This is what is meant by the return of kundalini to mooladhara.
If kundalini awakens in an individual chakra, the experiences which are characteristic of that chakra will be brought into consciousness. This may also occur when one does the practices for an individual chakra. For example, swadhisthana practices will raise joy; manipura practices will increase the selfassertion; anahata stimulation will expand the love; vishuddhi practices will awaken discrimination and wisdom, and ajna practices will increase the flow of intuition, knowledge and perhaps extrasensory abilities and so on.
If the nervous system is highly aroused, we may have other faculties opening because of the general arousal of the brain. This probably results from stimulation of an area in the lower end of the brain called the reticular formation. The function of this area is to rouse the whole brain or to relax it, as in sleep. The reticular formation and related areas have an inherent rhythm which is responsible for our sleeping/waking cycles, but it is also largely activated by sensations from outside - by light, sound, touch, etc., and from inside via the autonomic nervous system. It is the latter which seems to account for the more general arousal caused by the kundalini practices and other powerful yoga practices such as kumbhaka or breath retention.
