“As long as you have not grasped that you have to die to grow, you are a troubled guest on the dark earth.”
Attributed to Eliade in The Little Book of Romanian Wisdom (2011) edited by Diana Doroftei and Matthew Cross, this appears to be a translation of the last line of the poem "The Holy Longing" by Johann Wolfgang von Goethe, which, as translated by Robert Bly reads: And so long as you haven't experienced this: to die and so to grow, you are only a troubled guest on the dark earth.

“Live a good long life. Grow old and die after I do. And if you can, die laughing.”

This quotation was first used in print (and misattributed to Leonardo da Vinci) in a science fiction story published in 1975, The Storms of Windhaven. One of the authors, Lisa Tuttle, remembers that the quote was suggested by science fiction writer Ben Bova, who says he believes he got the quote from a TV documentary narrated by Fredric March, presumably I, Leonardo da Vinci, written by John H. Secondari for the series Saga of Western Man, which aired on 23 February 1965. Bova incorrectly assumed that he was quoting da Vinci. The probable author is John Hermes Secondari (1919-1975), American author and television producer.
