The self-realisation of Noble Wisdom by all the Tathagatas is the same as my own self-realisation of Noble Wisdom; there is no more, no less, no difference; and all the Tathagatas bear witness that the state of self-realisation is free from words and discriminations and has nothing to do with the dualistic way of speaking, that is, all beings receive the teachings of the Tathagatas through self-realisation of Noble Wisdom, not through words of discrimination.
