Fei-chi Hsien-pen (Abandoning the Traces and revealing the Origin) is the function related to the Subtlety of the Original Proclamation of the Dharma. Chih-i explains that in the past, because of heavy hindrances of five aggregates (Ch., Wu-yün; Skt., pan͂ca skandhāḥ) of sentient beings, the Buddha could not express the Origin, but only showed his recent accomplishment in the Traces. In the Lotus Sūtra, the hindrances of beings are wiped away, whereby it is necessary to abandon the teaching of the Traces in revealing the teaching of the Origin. (Vol. 2, Page 447)
