No clear that you can fuse imperatives, i.e., that ‘o kama jo e ijo ala li lon e (insa pi) lawa sina’ is grammatical. In adition, ‘lon’ is a prepsoition, so doesn’t take ‘e’. maybe just ‘o jo e ijo ala lon insa pi lawa sina’ “Empty your mind” (roughly, a ‘kama’ would probably help)
Not sure what ‘lon e’ is doing here; looks suspiciously like a copula, which tp doesn’t have. just ‘lawa sina li (maybe kama) poki pi ijo ala’. but I don’t thnk ‘poki pi ijo ala’ is very good for “empty vessel”. Hows about ‘o weg e insa pi lawa sina’?
