“Thoughts manifest themselves within emptiness and are reabsorbed into it like a face appears and disappears in a mirror; 
the
 face has never been in the mirror, and when it ceases to be reflected 
in it, it has not really ceased to exist. The mirror itself has never 
changed. So, before departing on the spiritual path, we remain in the 
so-called "impure" state of samsara, which is, in appearance, governed 
by ignorance. When we commit ourselves to that path, we cross a state 
where ignorance and wisdom are mixed. At the end, at the moment of 
Enlightenment, only pure wisdom exists. But
 all the way along this spiritual journey, although there is an 
appearance of transformation, the nature of the mind has never changed: 
it was not corrupted on entry onto the path, and it was not improved at the time of realization.”  ~ Dilgo Khyentse Rinpoche
