Q: excellent reference . Like other reviewers, I agree that a book is no substitute for instruction by a teacher.  Nevertheless, this comes as close (for the Yang style short form) as anything I've found.  Even if you have no interest in the martial aspects of taiji, having the potential applications of the form enriches practice.  I found the illustrations clear.  I own a half dozen or so books on taiji, and this is the only one I regularly consult

Q: I officially hate this book! . I, also, must second Mark Twain. This book is a waste of time! Why do teachers make us read it when we should be reading Tolkien, GK Chesterton, CS Lewis, and the like? Agh. Then, that could just be my wacky taste in novels...     But this was bad. Oh my gosh!!! The descriptions were ALWAYS needlessly long, the conversations ALWAYS needlessly long, the... blah, blah, blah, blah. That's what the whole thing was. Blah. The whole plot could have been totally condensed to a hecka short 200 pg novel and it would have been a million times better! Maybe even good! And I like long books!     This book is terrible. Listen to the warning of a fellow voracious reader and do not waste your time!

Q: Enjoyable by young and old alike! . The earth is surrounded by a sinister presence - a dark, foul fog that is the tool of an ultimate evil - whose ambition is to enslave the planet with the complete removal of free will. Three magical beings, Mrs Whatsit, Mrs Who and Mrs Which - witches, angels, demigods perhaps - appear to Margaret and Charles Wallace Murry and their friend, Calvin O'Keefe, to persuade them that it is their destiny to battle this evil on its own turf and to rescue Margaret and Charles Wallace's father. Dr Murry has been missing for some months and the kids learn that he has been captured by the evil while he was "tessering", traveling time and space in the course of his scientific research.    While the writing is straightforward, well crafted and obviously aimed at a younger audience, "A Wrinkle in Time" is nonetheless a fast paced enjoyable tale of good vs evil that combines elements of science fiction, fantasy and magic even adult readers will flip through relentlessly. But there are lots of life lessons, issues and moral themes sprinkled throughout - low hanging fruit just waiting for the eager child, the observant questioning teen, the confused parent or thinking adult to pick and chew on, as it were - the coming of age realization that parents are not infallible; the cruelty of malicious gossip; God and evil; the awkwardness of romantic adolescent relationships; the potential destructiveness of pride or vanity; the marginalizing of people who are different; the enormous difficulties of selflessness; the understanding that all life's questions will not be answered; and more.    While some readers criticize "A Wrinkle in Time" as being overtly moralist, I felt somewhat differently. It was clear to me that religion and, in particular, Christian symbolism was present but I felt that L'Engle let it sit quietly just beneath the surface and the story never became even remotely preachy.    It is little wonder that "A Wrinkle in Time" has been elevated to the status of children's classic and continues to be enjoyed by adults and children alike more than 40 years after it was first published for a grateful reading world.
