Six ways of clearly perceiving presently existent object based on the outflow and no-outflow wisdoms， as explained in the Yoga^ca^ra school. These are: （1） thought observation 思现观、wisdom which arises from thought based in feelings of joy. （2） faith observation 信现观; firm outflow and no-outflow based faith in the three treasures. This is a view that is not subject to backsliding. （3） precepts observation 戒现观; no-outflow precepts， which make the vision more clear. （4） the observation of the wisdom of reality 智谛现观; the a priori and a posteriori wisdoms that observe suchness in the paths of seeing 见道 and cultivation 修道. （5） observation of extensive wisdom of reality 边智谛现观; the mundane and transmundane wisdoms that are based on the manifold marks of suchness. ⑥ final observation 究竟现观; the ten no outflow wisdoms 十智 that are present at the final stage.
