The Holy Grail is a metaphor for nirvana, a state of being. The old texts point us to look where it is darkest and where there is no path - which points to the unknown, the willingness to let go of whatever is familiar... We might not reach nirvana in these 40 minutes, but we may get a glimpse of a deeper peace beyond the mind. We open our heart-space on a rolled up blanket, we sit, breathe and dive deeply into our being. We practice a few standing poses to reassure our mind and spirit, and sit again to see if we can let go some more. Try it out!
