Life is not a problem to be solved but a mystery to be lived. Instead of measuring our progress we engage in the practice with our entire being. This opens us up to the "light" that is in us and around us and we can experience a joy and connection with life that is beyond measure.
The way we think, feel and experience on retreat is not different from the ways we approach our experience in daily life. Whatever shows up is met with kindness - nothing is excluded. Our difficulties then become the manure for our transformation.
By turning inward we meet our shadows that we so easily can see outside of us and around us. Only by meeting our own shadow with love we can create integration and better social worlds. Looking at the body we can see how each part is communication, cooperating with each other.
For those, who struggle with the advaita/ non-duality teachings, the yoga also offers the alternative and/or additional practice of "surrender to God", a devotional practice. Readings of the mystic Kabir are used to illustrate the devotional aspects of the yoga practice as lied down in the Patanjali Sutras.
Yoga should not get confused with the circus like postures we see today. It is meditation in movement, slow and inward focused. The quietening of the mind, until it can experience the silence within and around us, is what we are looking for. The practice is one of simplicity and kindness, no striving.
