Namaskaram Peace guru,
I practice and teach Isha Classical Hatha Yoga. We teach yoga in its purest form, as it was practiced and ‘transmitted’ by the very first yogi, Siva. The practices are, as intended, deeply spiritual and require a conducive atmosphere in order to be taught, as yoga was always about a transmission of energy rather than just bending the body and stretching.
You can take a look at the teaching of Sadhguru Jaggi Vasudev on Youtube. My website is www.yogalogic.co.uk
Please feel free to ask me any questions you want to
