The birds are saying

 Today is ganapaty visarjan

It is sending off of God Ganesh

We had him over on 5^th and there was celebration for 10 days, n now

Today we are sending him off with fondness and love

On 15^th sept

Some wonder why this process? Some debate the whole process

Well here is my take on this  -

Is this not what Life is

We are born  - (ganpati coming)

We live life joyfully  (the celebration)

And then we leave  (visarjan)

The watery way ahead
