The first, and most advanced path of Raja Yoga is described in the first chapter of the "Yoga Sutras of Patanjali", called the "Samadhi Pada" or the chapter on meditation and super-consciousness.  This classical definition of yoga as "stopping the disturbed mental waves" describes five kinds of thoughts: right understanding, wrong understanding, imagination, sleep, and memory.

Some of the puzzles that people list for the public get indexed by the search engines (like Google). Some people find those puzzles and cannot figure out how to make a puzzle of their own. So this page now has the navigation sidebar.

There are now buttons on the puzzle so that you can get a clean page, in either HTML or PDF, that you can use your browser's print button to print. The PDF format allows the web site to know how large a printer page is, and the fonts are scaled to fill the page. The PDF takes awhile to generate. Don't panic!
