Diṭṭha: 1. seen — Since sight is the principal sense of perception as well as of apperception (cp. cakkhu), that which is seen is the chief representation of any sense-impression, and diṭṭha combined with suta (heard) and muta (sensed by means of smell, taste and touch), to which viññāta (apperceived by the mind) is often joined, gives a complete analysis of that which comprises all means of cognition and recognition. Thus diṭṭha+suta stands collectively for the whole series; 2. known, understood; diṭṭha pañha a problem or question solved; 3. (adj.) visible, determined by sight, in connection with dhamma meaning the visible order of things, the world of sensation, this world (opposite samparāyika dhamma the state after death, the beyond). Usually in compounds: diṭṭhadhamma, of this world, in this world; diṭhabhinibbuta, attained to Nibbāna in this birth; ditṭhanibbāna, earthly; diṭṭhasukhavihāra, happy condition (or faring well) in this world; diṭṭhavedanīya to be perceived in this condition
