This guide is the most complete and clearly communicated sanskrit reference for yoga that I have ever seen. I am a yoga teacher trainer and this will become my constant companion for both myself and to use in our trainings. It includes a comprehensive list of asana names and translations presented in alphabetical order with very, precise linear illustrations. This section alone is invaluable. The accompanying CD states the sanskrit term twice so that you may repeat it back and follows with the English translation (so you know the meaning of what you just said!). In addition to asana, the guide includes the sun salutation sequences, the first 3 astanga sequences, seven common mudras or hand gestures, common chants for your practice, several of the key sutras and a vast collection of yoga terms- numbers, yamas, niyamas, animals, bandhas, cakras, body parts and more.
