Academic Resources

Yogis/Yoginis in the state of yoga nidra it the Sitaram Yoga Studio in stroud

It is always better to practice yoga nidra than to talk or read about it! But there are so many useful articles and books to deepen our analytical understanding of the practice, and to read these can be helpful. So here we have brought together many useful yoga nidra resources, articles to read, and research to consider.
We hope you find these resources helpful in your practice of yoga nidra, and if you know of other articles that you feel would be helpful to share here, please do let us know.

Defining Yoga-Nidra: Traditional Accounts, Physiological Research, and Future Directions

This is a valuable read for anyone interested in yoga nidra. It was published in the US publication  International Journal of Yoga Therapy in 2013 [No 23 (1)] and is co-authored by Stephen Parker, Swami Veda Bharati (disciple of Swami Rama of the Himalayan Institute), and Manuel Fernandez. The article sets out some useful history and development of yoga nidra, as well as summarising some key research into the topic. The authors propose four different 'levels' of yoga nidra practice, including a fourth level (turiya) which has yet to be demonstrated under controlled conditions.  Interestingly, this article identifies Satyananda yoga nidra TM as 'preliminary practices' to yoga nidra, and also implies the possibility of 'spontaneously arising' states of yoga nidra which occur with practice. Certianly worth attention and discussion. 

Yoganidrā: an understanding of the history and context

We are delighted to be able to recommend this excellent history of yoganidra, both as a concept in the epic Indian literature and in the puranas, and in more contemporary developments. We applaud the intelligent scholarship of Dr Jason Birch and Jacqueline Hargreaves, and encourage anyone with an interest in the history of yoganidra to read their piece. This is now a set reading text for our yoganidra facilitator training courses.

Yoga nidra increases Dopamine levels

Troels W Kjaer et al  (2002)  Increased Dopamine tone during meditation-induced change of consciousness.

In Cognitive Brain Research 13 (2002) 255-259. 

This Copenhagen study demonstrated the first in vivo association between levels of an endogenous neurotransmitter (dopamine) and conscious experience: yoga nidra practice increased dopamine release by 65%. This is the first evidence at a synaptic level of the capacity to regulate conscious states and has wide relevance. 

Swami Satyananda on the origins and development of his approach to yoga nidra:

“The practice of yoga nidra is very old. You can still find references to it in the tantric texts. However, I have revised this ancient tantric teaching and brought it into practice. Yoga nidra is intended to use the mind to transcend the mind. Somehow I discovered that yoga nidra was beneficial for my own personality, and then I saw that it would also be useful for spiritually minded people, especially in the beginning. Of course, I had no mental or physical problems as such, but everybody has spiritual problems. Therefore, I discovered yoga nidra for myself in order to solve my spiritual problems".
