Later Tibetan Buddhist thinkers like Shakya Chokden would also work to show the compatibility of the Alikākāravāda sub-school with Madhyamaka, arguing that it is in fact a form of Madhyamaka. Likewise, the Seventh Karmapa Chödrak Gyamtso has a similar view which holds that the "profound important points and intents" of the two systems are one. Ju Mipham is also another Tibetan philosopher whose project is aimed as showing the harmony between Yogacara and Madhyamaka, arguing that there is only a very subtle difference between them, being a subtle clinging by Yogacaras to the existence of an "inexpressible, naturally luminous cognition" ("rig pa rang bzhin gyis ’od gsal ba").
