Yesterday a student suggested that Zen might be a path towards a "coma-like state". This was an interesting observation - and considering the way Zen can be used, perhaps in some cases his description was right!
This got me thinking about the Heart Sutra and why, for me, it is more liberation than lobotomy. I came upon the term, "No path." Zen is about living in the present moment. If you are walking "No path" then every step of the way you are expressing a preference. Forwards? Backwards? Sideways? Stop? With no path to follow, you choose.
The rest of Zen is just a support mechanism for ensuring that every step of the way we really do express a preference, and not just get jerked around by cravings.
