HUMAN BEING A COMBINATION OF THREE ELEMENTS, THREE ELEMENTS THEORY, FIVE ELEMENT THEORY OF LIFE, THREE ELEMENT THEORY OF LIFE vs. FIVE ELEMENT THEORY OF LIFE, HUMAN BODY MADE UP OF FIVE ELEMENTS :

ACCORDING TO THE FIVE ELEMENT THEORY OF HUMAN BODY :

According to Lord Shiva : Five Elements of Life(s) are :

1. Fire (Agni)   -Indicates Electron, Proton, Energy.
2. Water (Jal)   -Indicates Liquid State of Human Body.
3. Air (Vayu)    -Indicates Gaseous State of Human Body 
                  (Atomosphere).
4. Space(Aakash)-Represents- Empty Space/Universe in Human Body.
5. Soil (Mitti)  -Indicates The Elemental State of Human Body.

ACCORDING TO THREE ELEMENTAL STATE OF HUMAN BODY : 

HUMAN BEING AS A COMBINATION OF THREE ELEMENTS :
[Based On Satsang of Sant Sri Asaramji Bapu] : Human body is a combination of folliwing three element :.

1. Animalistic element,
2. Human element and
3. Divine element.

Animalistic element, of course, animal like behaviour meaning indiscriminate eating habits, disregarding parents, and the social norms. Just like cattle, which is governed by whims and fancies of the mind.  This is animalistic element. Human element, of course humanistic behaviour, meaning to have appropriate mode of living, good morals and ethical values, to keep good company, to respect parents and Guru (Teachers).
Divine element- when one comes in contact with Saints (Good Person or Plesant Human Being)  and Satguru (True Friend or Teacher or Guide) and undergoes spiritual practises doing Sadhana (Practicing God), Jap (Speaking God or Spiritual Lessons), Dhyaana (Meditation), austerities, fasting etc., the divine element develops.
A self-willed person has more of a animalistic element. Whether he is your son or a brother, but he would harass you because of increased animalistic element. As animal kicks every now and then, dog barks on the slightest provocation, likewise, one with animalastic element will lose his temper, develop love and harted (Raga-devesa) on petty subjects.  He is always in pursuit of satisfying his animalistic Vasanas (sensous) desires.
He would develop Raga towards the things which fulful Vasanas and develop Dvesa towards the obstruction in satisfying Vasanas. In fulfuilling Vasanas if one meets a obstacle from a person of stronger stature, fear grips him, resistance from peers will incite him to compete and interference from weaker persons sould make him angry.  Thus the inherent divine energy in human beings is wasted in Raga-devesa, fear, anger, struggle, and rivalry.

There are people who are diligent in performing their own duties and have more of a human element. They pay less importance to Raga-dvesa, and even if it develops they take care of it. Inspite of having developed human element, if his animalistic element dominates over the former, he is born as an animal in his next life. For example, King Nrg. although he had humanistic element, because of predominant animalistic element he had to remain in a well as a chameleon.
If one has predominant humanistic element, after death he will again get a human body, and if one persists in developing divine element along with human element, he leads a happy and peaceful life over here and after death he will go to God's adobe. But if he completely develops divine element then he would be worshipped like God in this very life.
There are also many such intellects who do not believe in God and they fritter away all their intelligence in amassing bodily conforts and luxuries.  Such intellects consider themselves to be superior, and other to be inferior, though theyt themselves are also beseiged by lowly thoughts, because they consider the body, which is heading towards death every moment, to be 'I' and its status, prestige, and power to be 'mine'.  But, those gullible fools do not realize that, just as a mouse can not escape from the clutches of a cat, likewise, none can escape the jaws of death. Nobody knows when it will swallow.
American newspapers reported that Abraham Lincoon's ghost was seen in White House. Abraham Lincoln was a humanist. Had he developed his divine element also, he would not have become a ghost.
After death some people become ghosts.  At the time of death, one with predominant animalistic element becomes devoid of consciousness.  Just after death subtle body remains in that surrounding for a 1.25 mahurt (approx. 2 hours) in non-cognitive and unconscious state. Because of Vasanas the Jiva(Life / Human) tries to re-enter the body but it cannot. Then teh subtle body takes re-birth according to its Vasanas. Suppose you are feeling thirsty, hungry, and sleepy at the same time, then you will fulfull the strongest desire first.  Likewise, after death, the Jive(Life/ Human) takes re-birth according to animalistic or humanistic desire whichever is stronger.
Very much akin to, after dispersal of a gathering, a drunked would rush to a bar, gambler to a casino, a gentelman to his duties, and a spiritual aspirant would engage himself in spiritual practices or go to an Ashram(Holy Place in Hindu Culture). Similarly Jiva(Life / Human) goes to different YONI(different forms of life like animal, human, bacteria, virus ... etc)
Assuming someone has desire to indulge sensual plasure of the body and at that moment if he meets with death then a according to karma(our holy duties) and vasna(our animalistic behavours), the jiva eventually, through the medium of moonlight or rainfall, gets into foodgrain or fruit, etc., which is subsequently eaten by humans or other living beings. Jiava finds mother's womb according to its Vasna, or else the jiva will find its way to a gutter.  What a powerful man he was but now his condition is deplorable! After many such failed journeys, if the circumstances become favourable, it finds an opportunity to stay in womb and subsequently takes birth.  Again he performes karmas in accordance with his desires and creates many new desires.

To recapitulate, both the animalastic and humanistic elements lie dormant in everyone.

That way, the jiva gets power from the Divine element, but because it does not contemplate on the divine element, sometimes it goes to pasu yoni (animal mode/form re-borth in hindu culture) sometimes to manusya yoni (re-birth as a human), and sometimes by gentle and pious behaviour it goes to deva yoni (demigod) and comes back to a lower yoni after enjoying the fruits of meritus (punya).

Fortunate, indeed, is one who takes shelter in God's name to develop divine element and does sadhana to achieve the SUPREM LORD, and does benevolent works for mankind.  He serves neither for heaven nor fame, but just to please God. Benevolent works help in developing antar-atma (inneer self) and enhances atmabala (Power of Self). Divine element assists us and rightly inspires us.  Thus, one who strives hard to awaken divine element and remains alert is intelligent in human world. Fortunate is he who performs benevolent works to develop the divine element for getting divine inspiration, knowledge, meditation, and peace.
