we can an external object or person, for we are the knowledge itself. Besides this, few
people are keen to let doctors open their skulls and look inside.
Neurosurgeons and yogis share common ground because both aim to know the truth
and reality of themselves. It is the approach which differs. While scientific researchers
have approached the brain objectively and have attacked and dissected it with knives,
probed it with electrodes, photographed and X-rayed it, stimulated and drugged it in
order to mechanically and externally manipulate its circuits into giving up their secrets,
yogis decided to scientifically discover the secrets of the brain by experiencing it directly
through meditation. Their findings agree with those of modern science.
Yogis discovered through meditation that within their bodies were circuits and centers
with both physical and psychic components that they called nadis and chakras. Though
we take this for granted now, we must remember that these studies were made thousands
of years ago without the aid of modern microscopes. Not only did yogis achieve a
wonderfully complete and practical system of techniques, but way back then they also
based their techniques on solid scientific research, the discovery that there are six major
primary centers in the body, the chakras, in a hierarchical, interconnected network within
the spinal cord. They also saw that each chakra had its own definite physical,
psychological and behavioral characteristics, connected to the brain by a network of
energy flows, all of which did not necessarily correspond to purely physical structures.
They also discovered many secondary centers which were subsidiary to the primary ones.
The chakras in the spinal cord were found to be points manipulated by focusing
attention, mental and psychic energy, breath and body postures, so as to derive certain
physical and psychic experiences. The techniques allow us to learn to control the most
basic and vital instincts and needs of body, emotions, mind, psyche and spirit. Recent
discoveries from neurophysiology and anatomy show that vital nerve plexes and
endocrine organs exist within the body, spine and brain and correspond to the levels
described by yogis. These findings support the claims of yogis that their system is more
than just mere exercises and relaxation. It is a method supplying the tools to control our
body, mind, metabolism and personality.
The triune brain
Dr. Paul MacLean, neurophysiologist and head of the Laboratory of Brain Evolution
and Behavior at the National Institute of Mental Health, USA, has demonstrated that the
brain of man is functionally divided into three main areas, three interconnected biological
computers, each with its own special intelligence, subjectivity, sense of time and space,
memory, motor and other functions. (1) Each brain corresponds to a separate
evolutionary step and is distinguished neuroanatomicalty and functionally, containing
strikingly different distributions of the main neuro chemicals in the brain, dopamine and
serotonin. If we look carefully into these levels and compare descriptions of
neuroscientists and yogis we see that both were saying the same thing.
