'detachment', seclusion, is according to Niddesa, of 3 kinds: (1) bodily detachment (ka^ya-viveka), i.e. abiding in solitude free from alluring sensuous objects; (2) mental detachment (citta-viveka), i.e. the inner detachment from sensuous things; (3) detachment from the substrata of existence (upadhi-viveka).
In the description of the 1st absorption, the words "detached from sensuous things" (vivicc' eva ka^mehi) refer, according to Vis.M. IV, to 'bodily detachment'; the words "detached from karmically unwholesome things" (vivicca akusalehi dhammehi) refer to 'mental detachment'; the words "born of detachment" (vivekaja), to the absence of the 5 hindrances.
