Some thoughts on yoga.
My first acquaintance with yoga asana, was self–initiated at home with a book, when I was in my youth. Because I didn't felt comfortable in my body. No, my parents didn't used that book. The book stranded somehow in our household. Until I read it on the book cover I never heard about the word 'yoga' before. I was always very ashamed about my body physically and carried out the asana hidden. It looked and felt terrible. Despite that, I even put together a 'full workout plan' with asana I might be able to do, if I proceed.
Later on, I went to Hatha-Yoga classes, once attended a Kundalini yoga class and then learned a lot about the body and the physics of asana in Iyengar-Yoga classes. 
I'm working on some Ashtanga yoga series at home now. Just because "I don't know why". I felt the routine keeps me together in those strange times. And I like how they flow.
