You’ll know how you’re doing in a pose by listening to the sound of your breath. It gives you immediate feedback. If your breath becomes strained or rushed, see if you can slow it down. Focus more on the exhalation, which is the calming portion of each breath. Elongate your exhalation, making it a bit longer than your inhalation. If you try this and find that you’re still unable to slow your breath, it’s time to rest. Check in with yourself, and see if you’re working too hard. Consider moving into Balasana (Child’s Pose). You don’t have to hold an inversion for 7 minutes; it can be 5 seconds with beautifully integrated breath.
