This book works, as I did the first 40% of the exercises in this book approximately a decade ago. One thing the
buyer needs to be aware of though is that they should think carefully about why a book that allows you to
multiply two multiple digit numbers in your head at near calculator speed sells for such a low price. Now (2012) there
is a new edition by the same authors so this knowledge is still in print (it may be slightly different as I have not
reviewed the newer version).

The reason this book is so low priced is because the source of this knowledge is not given. Therefore it is up to me
to tell you that this is not Raja Yoga (which enables you to do much the same things) but some other source. As most
paranoid readers of this review have guessed, this source is infernal. Now the proof:

1. The book is called 'Mathemagics', which is not a real word, and hence, with a cute, made up, black magic word, the
corruption process begins.

2. If the diligent reader of this book is not wealthy, by the time he or she starts multiplying five digit numbers
in their head, they could suffer a nervous breakdown as their belief systems would be damaged too much. The
combination of weakened mental state and infernal knowledge loaded into their brain might lead to possession,
in 1 out of every 5,000,000 cases.

3. There is always a good way to achieve a result, and this book is not it. Study Raja Yoga instead. I will vouch,
that it is sacred technology. I do not vouch for anything else in Yoga. Remember what anthropologists say :
your culture is your belief system.
