Sīvathikā: 'cemetery contemplations', as described in D. 22 and M. 10, have as their objects a corpse one or two or three days old, swollen up, blue-black in colour, full of corruption; a corpse eaten by crows, etc.; a framework of bones; flesh hanging from it, bespattered with blood, held together by the sinews; without flesh and blood, but still held together by the sinews; bones scattered in all direction; bleached and resembling shells; heaped together after the lapse of years; weathered and crumbled to dust. At the end of each of these contemplations there follows the conclusion:;This body of mine also has this nature, has this destiny, cannot escape it.; Similar are the 10 objects of loathsomeness asubha.
