Literally, the "buddha-way," which means the path to the buddhahood, but also often refers the Buddha's enlightenment in itself; buddhahood. The terms seems to have developed in East Asia without a Sanskrit equivalent (although it can be equated with the Indian concept of bodhi), often used to indicate the enlightenment which is the original endowment of all sentient beings. See, for example T 842.17.913c (圆觉经).
