Grammatical Analysis
Arūparāga: [m.] Desire for immaterial existence; lust for the formless. Formed by arūpa (formless, immaterial) + rāga (desire).
Orthodox Definition
Arūparāga is the seventh of the Ten Fetters. It is the extremely subtle attachment to the Formless Absorptions (arūpajhāna)—such as the base of infinite space or infinite consciousness—and the desire to be reborn in the Immaterial Realms (arūpaloka), where beings exist purely as consciousness without physical bodies.
Because these formless states are characterized by unimaginably vast lifespans (up to 84,000 aeons) and absolute stillness, the mind naturally craves them as a false sanctuary. The Buddha identified this subtle craving as a trap, noting that even the highest formless beings eventually die and return to lower realms if they are not liberated. Like rūparāga, it is permanently destroyed only by the Path of Arahatship.
