It would be lovely if your yoga and meditation practice spared you from that moment that occurs every now and then, when you absolutely feel like you are just going to lose it. Yoga allows us to process stress in a healthier way but it does not negate the actual feelings that arise both in every day life and on the mat. The practice does, however, give us some tools to better cope with some of the stronger reactions we might have. Whatever your triggers might be for said potential freak out, we could all use a rescue plan for when we feel like we are at our wit's end and need to keep our cool.
See below for a super simple meditation that can be done anywhere, anytime. Eyes can be open if you prefer and you don't need to fold your legs into a fancy position (unless you want to!)
Breath Count Meditation:
Sit up tall and bring your attention to your breath. Eyes can be closed or open, with a soft gaze.
Begin to count the breaths up to the number 10:
And so on..
Once you reach 10, begin again. No worries if the mind wanders- just bring the breath back to the number you were last on and continue.
Repeat as many times as you like, whenever you need.
