““Kamalasila's Illumination of Centrism explains: Thus, those who cannot understand all at once that all phenomena lack a nature, for the time being, gradually engage in the lack of nature of outer objects on the basis of [them being] mere mind. Therefore, [ The Sutra of the Arrival in Lanka X.154ab] says: Apprehender and apprehended cease In those who look with reasoning. Following this, by gradually examining the nature of that mind, they understand that also the [mind] is without identity and thus engage in the profound way of being.””
