Glacial Acetic Acid Suppliers:

They who love thee on this earth, keep calling on thee and chanting thy beads
Lest thou forgetest.

They assign the credit of their hard work to your blessings
They keep you amused.

They come to thy temple with baskets of fruits, as if you were a glutton
They deny the same to their children.

They offer you milk for a bath and burn the ghee
They hardly understand the meaning of it.

They bring gold and diamonds. They come with beating of drums
They love to advertise their offerings.

They offer you a small bribe as advance for booty, called lottery
They love to dream.

I do not bow down at your door
I do not bargain for booty
Your promise of the heaven does not lure me
Your hell-fire does not scare me
I do not even know the proper method of prayer
I do not offer any thing to you
Ages have gone by and I have not seen you my lord
Yet my love for you keeps waiting for you
