When we are deluded about the natural state and roaming about in samsaric existence, is our nature in any way worsened? No, it is not. The basic state of Mahamudra, the natural state itself, is not spoiled by confusion. It does not change in any way whatsoever. Is the natural state of Mahamudra improved through being realized? No, it is not. It is not an entity or identity that can be either worsened by confusion or exalted by realization.
from the book King of Samadhi: Commentaries on the Samadhi Raja Sutra and the Song of Lodrö Thaye
