"Get into a freewrite head" - let the surprises flow out, like opening the flood gates, undamming the river.
Or ripping off a bandage too soon, and....

Now I'm unpacking a hymn you brought to mind:
... Guide us still onward to that blessed shore,
After earth's toil is o'er!

From a Christmas classic by George Cooper, poet,

born in the city of New York, May 14, 1840 ... educated in the public schools of his native city, and afterwards studied law ... After practicing for a short time, he renounced his profession to devote himself to the vocation to which his natural gifts inclined him. In his early years, he had developed a taste for writing, and before his sixteenth year had begun to contribute acceptable verses to several leading magazines.

--Judy Garland sang it? Never heard that version.
---- "Oh Beth-LEE-hem star," she sings, LOL.

Star of the East, Oh Bethlehem's star,
Guiding us on to Heaven afar
Sorrow and grief and lulled by thy light,
Thou hope of each mortal, in death's lonely night!

Fearless and tranquil, we look up to Thee!
Knowing thou beam'st thro' eternity!
Help us to follow where Thou still dost guide,
Pilgrims of earth so wide.

Star of the East, thou hope of the soul,
While round us here the dark billows roll,
Lead us from sin to glory afar,
Thou star of the East, thou sweet Bethlehem's star.

Oh star that leads to God above!
Whose rays are peace and joy and love!
Watch o'er us still till life hath ceased,
Beam on, bright star, sweet Bethlehem star
