In this task, you are given books product reviews in English language. The goal is to classify the review as "POS" if the overall sentiment of the review is positive or as "NEG" if the overall sentiment of the review is negative.

Let me give you an example: Hopeful for those who seek harmony in the world . I wouldn't recommend this to anyone who thinks that religious wars, repression of individual spirits or rape of the earth are good things. Those who seek peace, harmony, celebration of each of us and respect for  our earth will find this hopeful
The answer to this example can be: POS
Here is why: The overall sentiment of the review is positive as the reviewer mentions positive expressions such as 'hopeful', 'will find this helpful' etc.. Hence, the label is 'POS'.

OK. solve this:
Greatful for this book . Gives you so much insight into your own world.  Thank you for this book.  It has helped me see the truth as it really is.  Not how I would want to see it
Answer:
POS
