Arupa-Loka
From Theosopedia
(Arūpa-Loka) A Sanskrit compound from arupa, without form, and loka, world or plane, hence “Formless World.” This term appears several times in The Mahatma Letters to A. P. Sinnett and subsequent theosophical writings. KAMA-LOKA, Rupa-loka, and Arupa-loka (all Sanskrit words) are the three spheres of ascending spirituality into which the several groups of subjective entities enter. Arupa-loka is the highest state of Devachan (Heaven).
See Devachan.
