"Without the work of K Pattabhi Jois, Ashtanga yoga would have been lost. All modern practitioners of ashtanga yoga benefit directly or indirectly from his teachings".
K Patthabi Jois learned from his master Krishnamacharya-whose own master was Ramamohan Brahmachary.My own yoga teacher Nancy Gilgoff learnt directly from Pattabhi Jois - For me keeping close to the lineage is very important -I try my best not to dilute my physical yoga practise and continue to study the text of Patanjali ( Pattabhi Jois said he taught Patanjalis yoga), this alongside reading items by writers who have given a lot of time to research both the history, and the physical practise of Ashtanga yoga.
