Ashtanga Yoga, Dynamic Yoga, Integral Yoga, Iyengar Yoga, Jivamukti Yoga, Kundalini Yoga, Power Yoga, Sivananda Yoga, Viniyoga ... are only a few of the best known Yogastyles.
They have been developed for good reason. To cater for the different needs of students regarding constitution, age, cultural background, experience, ... and that is exactly the reason why each can learn from the other.

Many yoga practitioners & teachers limit themselves to the one style which suits them the most, and some of those have the bad habit to disparage other styles, maybe even completely dismiss them as a valid yogic path and claim sole perfection and attainability of yogic truths for their own only. Thereby the opportunity to learn something new from other teachers or even their own students will be lost.

To give yoga a chance, it is necessary to learn about other styles as well, decide which one (or two ) is the most suitable for oneself and dive deeply into it. Even if you know one style already, it will pay off to stay open for, or even try something new.
Finding a common denominator and integrating what you learned into your own practice, instead of concentrating on the differences, will open new perspectives into what you already knew.

In reality there are as many yoga styles as yoga practitioners. They just don't all need their own name (the syles ).

They all have the word (or more than that ?) - Yoga - in common, which is not 'to bind, joke, put together', but the actual real and already existing unity. How the different styles try to teach that, is the difference.

That is the reason why we continuously try to get guest teachers to come, and also wish to have a variety of teachers in the yoga studio. Use them !
