Everyone has to use you  at one time or the other.

When alone you are lifeless- just a piece of furniture!

When a human sits over you- life fills you!
You give and take power from people!

You have taken many avataras;
As the seat of Power,
As the seat of justice,
As the seat of solitude,
As the seat of contemplation,
As the seat of genius -

you have mystical powers!

You were a silent witness to the  heinous plans people sitting on you hatched and executed - you are squarely responsible for the blood bath that followed.

You have a bad quality, you always reflect the attitude of the person who sits on you. You have no attitude of your own.

You have unseated many  people  from powerful positions- unceremoniously!- you are a heartless thing!

Nobody knows what you are planning to do the next .
