《瑜伽》五十七二十二根中，問世尊依何根處，說如是言：「遠行及獨行，無身寐於窟」？答：依意根處。由於前際無始時故，遍緣一切所知境故，名為遠行；諸心相續一一轉故，無主宰故，名為獨行；無色、無見、亦無對故，名為無身；依止色故，名寐於窟。《攝論》第四云：「遊歷一切所識境故，名為遠行；為證此義，復說獨行，無第二故；言無身者，無形質故，寐於窟故，居在內故；言調此者，於如是心作自在故；難調心者，性𢤱悷故。」

In fascicle 57 of the Yogācārabhūmi-śāstra on the twenty-two faculties, it is asked: on the basis of which faculty locus did the World-Honoured One make this statement: "Travelling far and moving alone, bodiless, sleeping in a cave"? Answer: on the basis of the locus of the mental faculty. Because from beginningless time in the past it universally takes all cognisable objects as its domain, it is called 'travelling far'; because the moments of mind continue and turn one by one without an agent, it is called 'moving alone'; because it is non-material, invisible, and without resistance, it is called 'bodiless'; because it relies upon matter, it is called 'sleeping in a cave'. Fascicle 4 of the Mahāyānasaṃgraha says: "Because it wanders through all cognised objects, it is called 'travelling far'; to confirm this meaning, it further says 'moving alone', because there is no second; stating 'bodiless' is because it has no physical form; 'sleeping in a cave' is because it abides within; stating 'taming this' means gaining mastery over such a mind; 'the mind difficult to tame' is because its nature is stubborn and refractory."
