Jesus says: Be passersby

The Gospel of Thomas is a record of the sayings of Jesus. It is a Coptic text, discovered in the twentieth century, and generally regarded as authentic as the sayings included in the synoptic gospels of Matthew, Mark and Luke. A number of the sayings in Thomas have parallels with sayings in those canonical gospels, though many of sayings in Thomas appear nowhere else. The Gospel of Thomas is sometimes referred to as the fifth gospel.
Professor Marvin Meyer was acknowledged as expert on Thomas, along with expertise on other so-called gnostic gospels. (See The Gnostic Bible edited by Willis Barnstone and Marvin Meyer.) The following is from his translation and commentary on one of the deepest and most enigmatic of the sayings. (Note: The numbering is a scholarly convention not in the text.)
(42)
Yeshua said,
Be passersby.*
*Or, “Be wanderers,” or, much less likely, “Come into being as you pass away” (Coptic shope etetenerparage). A parallel to this saying appears in an inscription from a mosque at Fatehpur Sikri, India: “Jesus said, ‘This world is a bridge. Pass over it, but do not build your dwelling there.’”
The Gospel of Thomas: The Hidden Sayings of Jesus by Marvin W. Meyer
This is not only the shortest saying attributed to Jesus, but one of the shortest attributed to any wisdom master. Yet it is open to so much meaning. To begin with, ‘passersby” or “wanderers” might mean different things. And if it is “passersby”, as in the Muslim inscription on that mosque, a bridge is only one way to understand this.
Whether we are advised by Jesus, in just two words, to be passersby or wanderers, how exactly are we to be?
