The moment when I understood the importance of breathing was when I read this quote of Rachel Roy in the Yoga Journal

I had a really beautiful moment as a mom two or three days ago. I went to pick up my six­-year-­old at kindergarten, and I got to go inside her classroom and see some of her work. [For a writing assignment,] her teacher had asked how they get through bad situations, and Tallulah wrote “through breathing.” I was so proud of her.

One who sees that everything is equally coming from oneself, whether it is suffering or happiness, is considered the supreme yogi – Bhagavad Gita (6.32)
