"The teachings are not ideas to be studied, but a path to be followed."
~Tenzin Wangyal Rinpoche
This is a quote from the introduction to The Tibetan Yogas of Dream and Sleep by the above. Sensei recommends it, she does a lot of dream work, we can all benefit from reading it...and you know if she recommends it then it is full of direct, practical and actually useful information. The Internet Archive you will find it at in the link is really cool too. Enjoy!
