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
Example solution: POS
Example explanation: 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'.

Problem: zen keys is lifechanging . i had always had a semi-interest in buddhism, derived from ecstatic readings of 'dharma bums' by jack kerouac (another must-have), but disappointed as i couldnt find 'big sur' at the bookstore a month ago, i chanced upon the religion section, and zen keys shone out on the shelf, i picked it up, read a page of thich nhat hanh's contemplative prose, and immmediately bought and took it home devouring it in my bedroom for hours. Nhat Hanhs compassionate and understanding approach to Zen Buddhism makes learning about it easy, and also very rewarding. his take, which is no ones take at all but rather the truth, about zen makes for free-minded thinking thru the eight negations, mindfullness of everyday life, and the wisdom of the zen masters in the kung-ans at the end of the book. i cannot help but be forever changed by this simplistic yet beautiful overlay of Zen Buddhism. anyone, everyone, Americans and materialism and all, MUST read this, dont lose your life in forgetfullness and apathy and be lost in worldly pursuit, be a monk
Solution: POS
