Possessiveness is basically divided into 3 types;
Child - I like it I want it; momentary
Women - I feel secured I want it; Safety
Men - This is mine I want it, Ahankar
Every one of us have all the three states to varying extent in our mind some having C more and W less and M more, they may be basically as per the age and sex child or women or men.
In all cases it is the minds personification that it is spinning around that object let it be animate or inanimate, useful or less useful, it gives security or not does not matter and so on.
That is how the basic human mind works. Even at the death bed one thinks he wants to live further, and does not want to die even at 99 years.
The minute wonderful two way communication (always it is one way communication - the information goes to Aatmaa compulsorily) is there between mind and Aatmaa then the Possessiveness or பற்று நிலை will go away and Detachment or possessiveness-less state பற்றற்ற நிலை will come. This is not a very great thing that only Gnanis can do. When you mature (somebody even at 90 they donot mature) then this happens. That is the time one has control over their senses. In many cases this happens, once they are taken to a point of no return or something great happens eg. say diabetic; children dies in front of you, you loose many suddenly severely; you find that something yonder is controlling you when it dawns. But nowadays we are always going for alternative ; Sugar-Sugar free; Fat-Fat-less, Potassium-Potassium free, Sodium-Sodium less, Running short of money-Loan or Credit card and so on.
When at 61, when I went to CMC Vellore, and I saw so many, so many are suffering with so many serious diseases, slowly it dawned on me that attachment should be shunned for the body that is slowly I am having less possessiveness of many things which otherwise, I had lot of possessiveness of everything on the earth earlier. Of course you can write comparing possessiveness and attachment (also the personification of possessiveness) showing so many examples from our Hindu classical literature right from RV to Upanishads to Puranas.
Once when it dawns on you that you are possessive of this and that then you will start thinking of reducing the same.
Anyway you can write many many things, but I stop here.
