kadag Ari Nielsen (@anielsen): "The Option Method works best when a human questioner rests in what is called kadag in the Dzogchen tradition, or the Option Attitude in the Option tradition: the felt sense that all things are fundamentally OK. Then, the dialogue can help point out kadag from person-to-person. …" Kadag (Primordial Purity): Represents the essence (ngo bo) of the ultimate ground (gzhi or base). It is emptiness (shunyata), like a clear, stainless sky untouched by the clouds of illusion. Lhundrub (Spontaneous Presence): Represents the nature (rang bzhin) or expressive energy (thugs rje) of the ground. It is the unceasing, luminous manifestation of all phenomena.
