ओमित्येकाक्षरं ब्रह्म व्याहरन्मामनुस्मरन्।यः प्रयाति त्यजन्देहं स याति परमां गतिम्॥

Word by word
The verse says
Saying Om, the single syllable that is Brahman, keeping me in mind — whoever leaves, giving up the body, goes the highest way.
In plain words
After the technique, one syllable.
That is the whole instruction. Not a formula, not a sequence, not something to be learned from anybody in particular.
One sound, and what you are turned toward while you make it.
Where you've felt this · in family life
Your father has one word he says when he drops something, and it is not a curse. It is a name he grew up hearing his own mother say twenty times a day. He is not being devout when it comes out. It is simply the thing that is loaded, and it fires before he decides anything.
Going deeper
One syllable is a strange amount of equipment to arrive with, and the smallness is the point.
What is being described is compression. A long practice does not stay long. Over years it packs down into something that can be carried at speed — a word, a name, a sound that the whole of it collapses into when there is no time for anything else.
This is why the syllable alone is not a technique anyone can borrow. The sound is not doing the work on its own. It is a handle on something that was built over a long time, which is exactly why the verse pairs it with remembering.
The question it leaves you with is practical and slightly uncomfortable. Something is already loaded in you and comes out when you are startled. It got there by repetition, and you may not have chosen it.
