Why are these compartments inactive? Because there is no energy. The active portion
of the brain functions on the energies of ida and pingala, but the other nine-tenths have
only pingala. Pingala is life and ida is consciousness. If a man is living but is unable to
think, we say he has prana shakti but not manas shakti. Similarly, the silent parts of the
brain have prana, not consciousness.
So a very difficult question arises: how to awaken the sleeping compartments of the
brain? We know how to awaken fear, anxiety and passion, but most of us do not know
how to awaken these dormant areas of the brain. In order to arouse the silent areas, we
must charge the frontal brain with sufficient prana and we must awaken sushumna nadi.
For both these purposes we must practise pranayama regularly and consistently over a
long period of time.
Lighting up the brain
In kumdalini yoga it was discovered that the different parts of the brain are connected
with the chakras. Certain areas are connected with mooladhara chakra, others with
swadhisthana, manipura, anahata, vishuddhi and ajna. When you want to turn on an
electric lamp, you don't have to touch the lamp itself, you operate it by means of the
switch on the wall. Likewise, when you want to awaken the brain, you can't deal with it
directly, you have to flick the switches which are located in the chakras.
Modern science divides the dormant area of the brain into ten parts, whereas in
kundalini yoga we divide it into six. The qualities or manifestations of the brain are also
sixfold, e.g. the psychic powers. These manifest in different individuals according to the
degree of awakening in the corresponding areas of the brain. Everybody is not
clairvoyant or telepathic; some people are talented musicians. Anybody can sing, but
there is a center in the brain where transcendental music expresses itself.
Total and partial awakening
A genius is one who has been able to awaken one or more of the dormant areas of the
brain. People who have flashes of genius are those who have had a momentary
awakening in certain circuits of the brain. It is not total awakening. When the total brain
wakes up, you become a junior god, an incarnation or embodiment of divinity. There are
various types of geniuses - child prodigies, inspired poets, musicians, inventors, prophets,
etc. In these people a partial awakening has occurred.
Sahasrara is the actual seat of kundalini
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.
