• The brain does not heat up when thinking for long durations, if thinking of couple of things at one particular time, then it may heat up.

    But, scientifically it is proven that on average successful people use 5% of their brain's thinking power, using this power one can attain maximum successes.
In the mind, the tussle of thought currents continues unabated. The mind remains busy at all times. We could say, the function of the mind is to think and it is acting as per its nature! So let it go...Why mind it?

There is definitely something wrong in it. Think about a machine whose parts are made of metals. If the machine remains functioning without a break, day and night, what will be the result? It will get all heated up. Similarly, the brain, too gets stressed; when thoughts are generated on a continuous basis, it also gets heated up. Anger, tension, agitation - all these are the result of increase in the level of 'temperature' of the brain. Increase in the level of noise pollution is one of the reasons for hypertension, stress and depression. If the noise outside can create such a disastrous situation, think of the impact of internal noise - the dissonance produced by a multitude of thoughts.

If we do not think, how would we work and function? Thinking is not at all wrong. Just avoid unnecessary thinking that is similar to noise pollution. When a scientist creates an electric circuit, he is always cautious of the 'noise factor', which indicates the 'undesirable electrical disturbance' or the avoidable obstruction. In the presence of such disturbances, the circuit doesn't accept the signals of current properly; it doesn't allow it to pass through in the right measure, nor gives the desired output. Likewise, within the circuit of mind, due to the disturbance of useless thoughts, we are unable to take proper decisions. It hampers our sense of discrimination and a reasonable understanding of the issues.

Buddha used to tell his disciples often, 'Practise peace!' Sufi Saint Rumi proclaimed, "Get liberated from the imprisonment of frightening thoughts. Practise silence." When the mind "dies", silence prevails. Death of mind means controlling the mind to the extent of thoughtlessness. A state in which no useless or disturbing thought is permitted to evolve! Through this thoughtless or say mindful state, the fountain of bliss emerges!

To attain this state, gurus have stressed the need to connect with the inner Self, the source of peace and bliss. Upanishads proclaimed it as Atman gyan or Brahmn gyan. After practically realizing the inner Self through the third or divine eye, one can commence the journey of peace to reach the depths within and seek eternal bliss. A true spiritual preceptor activates the third eye of the seeker and enables him to embark upon his inner journey. In that blissful world, thoughts are not admitted. Bliss alone reigns! It is the ocean, diving into which you begin to experience peace.

Now, different brainwave patterns have different names, depending on their frequency. (The frequency is measured in pulses per second.)

So, for example, the “Beta” pattern is typically emitted when we are consciously alert, and is our dominant waking frequency. Think concentration, cognition. On the Hertz scale, this ranges from 12 pulses to 40 pulses per second (Hz).

Going deeper, “Alpha” is another brainwave pattern, which usually occurs when we are in a state of physical and mental relaxation, though still aware of the world around us. Think creativity and deep chill. It has a range of 8-12Hz.

There’s also “Theta,” which stands at 4-7Hz, and is often associated with daydreaming, or feeling very sleepy. Think meditation, intuition, memory. It’s also strongly associated with creative states.

Plus, “Delta” which is the stage between 0.1 and 4Hz, and really represents the lowest amount of activity possible.  This typically only occurs during deep sleep, and can also trigger growth and body healing.

At the opposite end of the spectrum, above Beta, there also exists “Gamma” which is a critical yet mainly supportive frequency, found to exist during certain Buddhist meditations. Think inspiration, higher learning, focus. Gamma exists at 30 to 100+Hz, yet never exists solely – it is always complemented by other brainwaves.

 

The brain starts overheating as a result of regulating these activities, processing trillions of instructions per second. The heating of the brain, if not controlled, can cause disorientation resulting in accidents and even death at the workplace. Alternatively, cold temperatures also impact worker health and productivity by reducing mental alertness. Almost 50 percent of the body heat is lost through the head making it vital to keep the head warm in cold work environments.
 

That, it leads to the perception of heat and temperature, ardor, enthusiasm.

Oven, to roast meat, raging core of an oven, faculty of thought, power of discernment and human emotion.

Triune brain:

The Survival Brain; [brain stem or reptilian brain: reacts to danger by triggering fight or flight mechanism. These reflexive behaviour insured survival.

The Emotional Brain: [limbic brain or mammalian brain]: triggers emotions that motivate behavior. The amygdala scans stimuli for cues of danger or inters, triggers emotions, and stores important evens in long term memory.

The Logical Brain (prefrontal cortex) handles language, reasoning, and emotional control so humans can intelligently solve problems and make meaning out of life events. This area of the brain does not develop fully untill matured-strengthen adulthood.

There are highly traveled pathways going from the emotional brain to the survival brain which activate automatic flight and fight reactions. There are also many pathways from the emotional brain to the logical brain, which is why our emotions color our thinking. However, there are fewer pathways from the logical brain to the emotional brain. No wonder it is so difficult to keep emotions under logical control.

Plural of paucity can be called as individualized plural.
