TiếpHiện is a Sino-Vietnamese term (Chinese 接现). The term did predate the Order of Interbeing's use in other contexts in Vietnamese, but was and remains uncommon. Tiếp means "being in touch with" and "continuing." Hiện means "realizing" and "making it here and now." The translation "Interbeing" (French: Interêtre) is a word coined by Thich Nhat Hanh to represent the Buddhist principles of No-Ego, Interdependent Origins and the Madhyamaka understanding of Emptiness. The order contains members of the "Fourfold Sangha" (monks, nuns, laymen, and laywomen) and is guided by the Fourteen Mindfulness Trainings .
