Arjuna, an Ashtanga yoga student & teacher in Germany, has a wonderful website with photos of each posture of Series 1 through 4 (!) plus Surya Namaskara A, Surya Namaskara B, and the Finishing Postures. He even includes details of the vinyasa count for each posture.
This is the only site we know of that has a systematic listing of photos of the 3rd and 4th series. Note that Arjuna says:
However, because I only did the primary and intermediate series under Pattabhis guidance, when I practice the advanced series I use the counting and method I have learned from some senior students of Pattabhi Jois.
- You cannot link to a unique posture directly to illustrate a posture name
- No transitions are shown
Arjuna has also posted PDF files with these photos by section, along with other useful information, like suggested adjustments (also with photos).
Warning: don’t try those advanced series at at home. There’s a reason why this stuff is only taught under the close supervision of an authorized teacher.
Arjuna leaves us with an interesting thought:
The “most traditional” form of Ashtanga Yoga still differs quite a bit from teacher to teacher.
Maybe Ashtanga Yoga is like yeast. If you put a bit of curd in milk, the yeast will transform the milk into curd. You can take your curd to any country, put it into milk and it will happen. – But the curd will always taste a bit different. The yeast is the same, but the milk changes. Likewise, Ashtanga Yoga has a different flavour everywhere, but it is still Ashtanga Yoga.
