I could not find the meaning of: "It may be tripping the light fantastic" and asked my American friend Robert, who used to be a teacher and who is also a reader of Heavenletters, to enlighten me, and since other translators may also find it difficult, here is his explanation:
Trip The Light Fantastic is a phrase used mostly in slang now. One of it's original meanings and the one most closely associated with it's use in this Heaven Letter is "A going from one place to another, a journey.
In slang, an example that can apply here is. 1. An intense, stimulating or exciting experience or to move in a pattern or dance-like motion expressing the joy experienced in a situation. In a sentence, I might say; I was so excited and overjoyed, I tripped the light fantastic.
I now translated it as: "It may be an exciting journey that makes you dance of joy."
