The greatest quality of person is to acknowledge. The other name for acknowledgment is thankfulness.

God Almighty blessed us with this life. This life is indeed unique. No elephant, tiger or galaxy can think like humans. They don't have a mind as ours. They don't have hands to hold nor feet to walk upright as we do. Our digestive system is unique. We eat food and it gets converted into blood and flesh.

A poet once said that he observed something unique,

"Whatever Miss T eats turn into miss T."

Miss T, a woman, eats food and when it goes into her body it turns into a flesh. It becomes part of her personality.

How does this happen? There are millions and billions of such things for which we need to be thankful.

We need to acknowledge God every moment. God has given us a chance to lead life in a good way. God gave us existence in this life. He provided us with life support system in the form of Earth, Sky and Sun. Then He gave us a greater opportunity to live for 50-60 years in this world with right conduct.

All these aspects of thankfulness are so multitude that you need to always in prostration and thankful to God. So the greatest virtue of person is to be thankful to God.
