Yoga Nidra is also called a yogic sleep. It is a combination of relaxation and visualization techniques and lasts about 30 minutes. A good yoga nidra session results in complete relaxation of your body, mind and spirit.
You practice in a very comfortable savasana position with the instructor reading the yoga nidra script.. During the first phase of the practice we concentrate on relaxation of the physical body and a regular still breath. The instructor invites you to use a carefully selected affirmation that you repeat to yourselves at the beginning and at the end of the practice. Visualization techniques enhance the relaxation and are supposed to help you to resurface emotions. You work with a “TV screen” which is the space between your eyebrows. This is where you project the visions during the practice.
During yoga nidra our brain switches between alpha wave which is the state between awake and asleep, beta waves (awake) and theta waves (dreaming sleep), so don’t be surprised to hear your yoga neighbor snoring during some parts of the practice
