The only book you'll ever need on yoga. After that, it's time to seek a teacher :)

Swami Janakananda has laid out clearly the ancient practice of Tantra for use in daily life in our own time. The writing style is so clearly descriptive and easy to interpret that anyone can practice with this thorough guide book.

Not to mention, the book can be followed up with courses in Sweden (and quite a few other sister school's around Europe), which has courses throughout the whole year, guided by teachers who are required to have at least 4 years of full-time training (usually 6), a practice which is more closely following the old ways of yoga, than what you typically find in a yoga class these days. This is yoga which is totally true to the traditional yoga, while incorporating modern scientific research.

Find in here asana programs, yoga nidra, meditation techniques, pranayama, tratak, the Tantric sexual ritual and lots of useful information.

It's also available in many other languages.
