Ācārya Sthaneshwar recommends haṭha yoga in the Antarāla course, so I'm hoping that those with more experience with this sampradāya can recommend some resources for those of us with no experience with haṭha yoga, especially since the Internet can so easily lead us astray. Which Youtube channel, website, book, ancient scripture, etc would those who've found success on this path recommend for starting our haṭha yoga practice? Thanks in advance!
