MAHADEV / Mahesh  (Shiva)
 

Mahesh (Shiva) is only superior among the three Deity. That is why he is called MAHADEV. He gave us Shiva Ling. He gave us all the symbols of Shiva, A (Ling), with the structural, physical shape. His concert is SHAKTI (PARVATI, DURGA) power, Shiva is satisfied with Power/ Force.
 

According to the Gita, impulse is Vegam or force. Lord Krishna says, "He who is able to endure here on earth, before he is liberated from the body, the force born of desire and passion, he is harmonised, he is a happy man".
 

Impulse is a mighty force. It exerts influence on the mind. It is a force suddenly communicated to the mind.
 

Lord Siva is the deity symbolically presents the controller of death/ destruction (the destruction is for further construction). Mahavishnu and Lord Siva are said to be connected through hearts (which only means inseparable) Vishnoasya hrudayam siva: Sivosya hrudayam vishno – says Upanishads and Yajurveda.
 

Symbolically Lord Siva has powerful fire in the third eye, powerful water and torrential air symbolically tied in the tuft and the snake around the neck (symbol of international medical association) and tri sool in hand. All the five respectively present destruction through fire, water (flood, etc) air (cyclone/ tempest, etc) diseases and using weapons. Parvati (means energy/force/sakti) is symbolically presented as the wife of Lord Siva. Through this combination of Lord Siva and Parvati, it is shown that the destruction for construction can take place with powerful application of any one or more of the above five. (Powerful fire, air, water, diseases and weapon only have the destruction capacity). Thus they become inseparable hence the concept of Ardhanaareeswara comes up. In fact the Brahma Vishnu Maheswara sankalpa and the Lakshmi Parvati Sarswathi sankalpa are the symbolic presentation of the life cycle spiritual- social and physical level when scientifically explained. Always the Hindus consider the knowledge, prosperity and sakthi/power in feminine gender. These explanations (of the gods) are the connecting layers of Vedic and puranic concepts of gods.
 

The most important is opening of the Third EYE – Pineal Gland --The pineal gland is a structure that lies in the very centre of the brain on the ventricular system. This gland is sensitive to light and secretes hormones called melatonin, which is related to mood, wakefulness, and other states of awareness. The Pineal gland represents the third eye of SHIVA  in the physiology.
 

The three eyes of Lord Shiva are often the focus of mythological interpretations and mystic curiosity. Representation of His manifestation in humanlike form should have shown only two eyes like the normal humans have. Is the third eye mere all egoric depiction? Or, does it signify some hidden facets…? In fact, the third eye symbolizes the source of sagacity – pure, discreet wisdom. This centre in the human body is hidden subtly in an endocrine gland inside the brain right behind the position (on the forehead) where the third eye of Shiva is depicted.
 

The Biophysical energy released from your body is called the opening of third Eye. A Third Eye- Name given to the process, whereby the full potential of man’s Biophysical, mental, and emotional energy released, integrated and focussed. The third eye opens only when the Shiva does the Tandav Nritya is done.
 

Incidentally Colin Wilson in his book THE OCCULT, says that occult power are within human body. “Researchers to the “PINEAL EYE” the organ in the brain that the Hindus declare to be the seat of the Occult power were assumed to be a vestigial eye although no one quite decides that use an eye would be in the middle of the brain.
 

In the present century scientists began to recognize an odd connection between the pineal eye and sexuality. It was established that the organ is a gland not a vestigial eye and that it produce a hormone that was labelled melatonin, melatonin is produced by the action for a certain enzyme upon a chemical called serotonin. 
 

The real mystery begins here. This chemical has been proved to have a great deal to do with evolution of species. The primates, Men, and apes have more serotonin than any other species. Which seems to be manufactured in the Pineal Eye. And one of its functions is to inhibit sexual Development and to increase intelligence. This seems to explain, why most intelligent human beings seems to be late developers sexually and why early developer are seldom. If ever remarkable for intelligence. Pineal Eye also called A Third Eye
 

However still, what is and who is Mahadeva is a subject totally different to explain

Tangible symbol of cosmic union
 

It is surprising that in India, the place of origin for Kama Sutra and Tantra, sex is something that is frowned upon or even feared. Most of us treat our sexuality as something that should be talked about in hushed tones.
 

This unnatural fear may have risen from the fact that we often do not understand the awesome force of sexuality. It is true that intense desire actually blurs the mind or even creates confusion and a feeling of insecurity. The reason behind this sense of insecurity is the truth that intense desire also means letting of the ego- to be completely selfless, to seek other’s pleasure before achieving one’s climax and to seek total oneness with the significant other. But to be completely abandoned without a thought to another thing is something that is not easily possible for most people. Our desire to escape from its overwhelming intensity alone is what creates an antithetic view of sex where none actually exists.
 

So we tend to view sex either in a positive light or in a negative light. But the truth is that the sexual force that is inside us is neutral and is multidimensional at the same time. It is intense, natural and healthy, and represents the power of creation itself. It is in truth the creative energy that is in it a divine and a spiritual force. For if this energy did not exist within us then we would not be able to replicate God’s an act of creation, the main stay of our existence on this planet.  
 

Our ancients have said that it is this same cosmic energy that is present in living beings as the sex force. So Hindu regarded this energy as sacred, something that is worthy of being worshipped, not fettered away. We also need to embrace the multidimensional nature of our sexual feelings. The human experience of the sexual instinct is never static, but it is ever changing. So it is physical, psychological, emotional and even spiritual. (That is opening of the third eye of Lord Shiva- Name given to the process, whereby the full potential of man’s Biophysical, mental, emotional energy released, integrated and focused. )
 

When we make offerings to the Lingam and invoke Shiva and Shakti, we are acknowledging and celebrating the fact that Shiva and Shakti are not separate. That is, as husband and wife, Shiva and Parvati may appear to be two but in facts they are but one. Hence we give so much importance to the Lingam in Shiva temples across region. The concept of unity is very relevant in family life as well. The husband and wife must live with one mind; they need to complement each other. The Shivalingam is a miniature representation of the egg-shaped universe.
