Sleep Well With TYN - Nirlipta

"We feel passionately that yoga nidra is one of the most vital forms of twenty-first century medicine and spiritual practice, and we are committed to sharing it as widely as possible. Yoga nidra is a great treasure, a potent meditative resource for healing, insight, and empowerment. It's a state of consciousness in which we are invited to re-encounter the essential truth of who we really are. Yoga nidra provides us with the opportunity to experience deep freedom."
