Learning From Ancient Yogis

My interest has been renewed in studying the ancient texts of yoga. In addition to the Yoga Sutras there are texts like the Hatha Yoga Pradipika, the Jogapradipika, the Bhagavad Gita, expositions by various masters like Vashista, Matsyendra and Gheranda. Plus thousands or tens of thousands of other shastras written anonymously.

I ask myself, "do I know more than these yogis?" If I disagree with something they have written, do I have the authority to disregard it and do my own thing? Why would I take their advice in some aspects but not in others? 

Like many other modern yogis, I have instincts and opinions about what is "right" in yoga and what is "best." Not to mention the powerful pull of capitalism that seems destined to drag yoga into the world of physical fitness. Who am I to say what yoga is or is not? Especially when there is documentation from yogis far greater than me.

At this point, I feel the need to be humble. Practice, be focused and studious. Read what these yogis wrote that has lasted thousands of years. Develop my own relationship with this powerful force we call yoga.
