Knowing this in full means knowing all things, or knowing the whole world or whatever it is that we must know, and knowing it truly. Putting aside the noble truths, to know anything in this world it must be known according to these criteria: know the thing itself, know what we must do in relation to that, and know that we have done that task. For example, a rice farmer must know what a rice paddy is, what task needs to be done, and how it is to be completed. This is knowing about farming. It is the same with other things. And so this same principle is applied to the four noble truths.

Ajahn Buddhādasa (1906-1993), Buddhadasa was a Thai Buddhist monk. Known as an innovative reinterpreter of Buddhist doctrine and Thai folk beliefs, he fostered a reformation in conventional religious perceptions in his home country, Thailand, as well as abroad. He developed a personal view that those who have penetrated the essential nature of religions consider "all religions to be inwardly the same", while those who have the highest understanding of dhamma feel "there is no religion"
