Malcolm: 
You mean rig pa. Rig pa is also empty, baseless, and not established 
in anyway at all. The Dzogchen tantras and Longchenpa declare this 
univocally.
    Retinue of nonexistent superficial appearances, listen!
    There is no separate object in me, the view of self-originated 
pristine consciousness. Passing away in the past does not exist. Arising
 in
    the future does 
not exist. Appearing in the present does not exist in any way. Karma 
does not exist. Traces do not exist. Ignorance does not exist. Mind does
 not exist. Intellect does not exist. Wisdom does not exist. Saṃsāra 
does not exist. Nirvāṇa does not exist. Not even vidyā (rig pa) itself 
exists. Not even the appearances of pristine consciousness exist. All 
those arose from a nonexistent apprehender.
-- Tantra Without Syllables.
This
 "nonexistent apprehender," indicates the union of the two truths. Even 
rig pa is something relative, that is why it is a path dharma, not a 
result dharma. It vanishes at the time of the result.
