SO, LET EVERY ONE DO WHAT THEY WANT TO DO.

What you say is 100% right... No Dispute.

There are and there may be people criticizing everything for criticizing sake.

And they are and they may do or act worse if they are in such a position.

And may be most of who criticize are of such.

Even I may be one among them,  

If the emotions and criticisms are based on envy or jealousy

Feeling helpless not to be able to loot the country (and live luxurious)

Like others in big positions are looting and living luxurious.  

But, to see and take even such criticism and jealousy positively is better and holistic.

Life (or what we call God) is the one who does, makes or causes the mistakes.

How ?

Through each one of us.

Through our thinking and doings.

As if we are thinking and doing for ourselves, but for the whole.

And the same life or God is the  one who does or makes or causes the corrections.

How ?

Through each one of us.

Through our thinking and doings.  

As if we are thinking and doing for ourselves, but for the whole.

Why and for what?

This is the way Life (or what we call God) does,  makes or causes the construction and growth.

The change. Growth of this world, life, God.

It is through mistakes and its correction (with criticisms) the world (life or God) has grown to this level and is going further.

The great magic of Life (or what we call God)

So, criticism and its seeking for correction and change is the criticism and seeking of the whole nature.

For growth and construction.

By and for life or what we call God.

As you may know it better, no construction is done without destruction and thought for destruction.

So, let every one do what they want to do.

Be it by ruling the way Indian rulers are ruling.  

Be it by corrective movements asking the correction they feel needed for the system.

Be it by criticism of those who are envious and jealous,

Feeling helpless not to be able to loot the country (and live luxurious)

Like others in big positions are looting and living luxurious.
