Sukkha-vipassaka: 'one supported by bare insight', is the commentarial term for one who, without having attained any of the meditative absorptions Jhanas, has realized only by the support of insight Vipassana one or several of the supra-mundane paths see: ariya-puggala In Vis.M XVIII, he is called suddha-vipassanā-yānika as distinguished from 'one who has tranquillity as vehicle' samathayānika. Though the primary meaning of sukkha as intended here is as stated above, subcommentaries e.g. D. Tīkā employ also the literal meaning of sukkha i.e. 'dry':;His insight is dry, rough, unmoistened by the moisture of tranquillity meditation.; This justifies a frequent rendering of this term by 'dry-visioned' or 'having dry insight', which, however, should not lead to misconceptions about the nature of insight meditation as being 'dry' or 'merely intellectual', while in fact the development of insight will produce rapture pīti and a sense of urgency samvega in the meditator.
