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.
