Without any limits

The thinking of a writer is without any limit, 

It never leaves topic and thinking as credit. 

The thinking brings a moment high in the sky, 

The next moment to the deep sea, 

It sometimes blows in the wind 

Sometimes sail in the water. 

Sometimes burn in the fire 

Sometimes thinking is very rare. 

Arrangements of words is having importance, 

Tied in a thread, like a necklace
