I didn’t start yoga on any given day. I don’t think anyone does. Instead I think we evolve towards it. I remember when I did my first asanas though. It was likely 1999 when I first browsed through a Sivananda Hatha text belonging to my brother. I remember putting myself through one of the 90 minute sequence of poses defined in the book and then grinning inexplicably at the end. That was a one-off practice and it would be a couple of years before I developed a daily habit.
