With regard to the truth itself, the common view held by Buddhists is that it is indescribable and inexpressible and can only be reached by intuitive insight through contemplation. What is the point then for the Buddha to teach truth? Chih-i argues that the Buddha’s teaching is necessary for the sake of liberating sentient beings. Truth has to be delivered when there is need for it, namely, living beings have a need to hear the teachings in order to eliminate suffering and attain liberation.
