With Advanced Fridays, Rita Keller accompanies advanced yoga practitioners and yoga teachers throughout the year. Each year has a thematic focus, which is gradually developed: once a month for 3 hours. The first part of the year 2021 will be based on The European Teachers Convention with Geeta S. Iyengar in 2009 in Cologne.
For B.K.S. Iyengar his daughter Geeta was the most important student, teacher and successor.
