The manuscript of this poem shows a small alteration in Traherne's hand in the second of these two lines. Where we now read 'true Ideas', there originally stood 'fair Ideas'. 'Fair' described Traherne's experience as he immediately remembered it; the later alteration to 'true' shows how well aware he was that his contemporaries might miss what he meant by 'Idea', through taking it in the sense that had already become customary in his time, namely, as a mere product of man's own mental activity.
