Lightness         (mental elements 36 and 37, Li1-Li2)

Lightness is the phenomenon that crushes the heaviness caused by elements such as sloth and torpor. It makes the mind non-sluggish, just as losing weight makes an obese person lively and nimble. It is like the state of mind-body that is present before a heavy meal, rather than after a heavy meal. Lightness simply indicates a state of mind free of sleepiness, lethargy, boredom, drowsiness, drooping, sinking, and so on. It is an essential wholesome element, meaning it is always present in some degree in all wholesome states of consciousness.
