Ever wondered what it's like to be conscious while you're sleeping? Well… turns out there's yoga for that: Yoga Nidra, or ‘yogic sleep’. Yoga Nidra refers to a state of consciousness between waking and sleeping, like that moment just before falling asleep. A major difference with meditation is that rather than focus, the goal in Yoga Nidra is to completely relax. In short: during a Yoga Nidra class, the yoga teacher guides you through a 60-minute supercharged power nap.Yoga Nidra has been around for a long-long time. The first mention of it is in the Mahabharata, a Sanskrit text that’s so old that nobody can figure out when it was actually written. It's basically the antidote to stress and anxiety for stressed-out peeps. Slowly but surely it’s also being adopted in treating PTSD patients. You don't need any yoga experience for our Yoga Nidra class.
