18.3.7

idáṃ ta ékam purá ū ta ékaṃ tr̥tī́yena jyótiṣā sáṃ viśasva |
saṃvéśane tanvā̀ cā́rur edhi priyó devā́nāṃ paramé sadhásthe ||7||

Here is one for thee, beyond is one for thee; enter thou into union with the third light; at entrance be thou fair (cā́ru) with [thy] body, loved of the gods in the highest station.
