虛空無為

(sa) ākāśa, one of the (sa) asaṃskṛta dharmas, passive void or space; two kinds of space, or the immaterial, are named, the active and passive, or phenomenal and non-phenomenal (i.e. noumenal). The phenomenal is differentiated and limited, and apprehended by sight; the noumenal is without bounds or limitations, and belongs entirely to mental conception.
