Using Yoga Posture Flows for NonDual Awakening

I have come across Gary's material just a week ago by accident and have read his "Happiness beyond thought" book plus wtached some of his youtube videos.
His clean and empirical view on things really resonates with me.

Do you have any experience with the material he presents? Do they lead to this magnificient calm thoughtless state he claims to have attained?

I just do the yoga flow in the linked video. Regarding theory, I follow Vajrayana path. I think that the material he presents could lead to the magnificent thoughtless state he claims to have attained but perhaps not the understanding as to how it happened.
