In plain words
When all these elements dissolve, the space in each of them remains spotless. In the same way, meditate, with a meditation beyond compare, on your own being: it pervades each and every form and yet has not a single stain.
Word for word
As the space in each remains pure when all these elements dissolve, so, though pervading each and every form, practise meditation beyond compare on oneself, which has not a single stain.
