One's own home

Moving hands affects my brain.
Knocking the stands, riding the train.
I've got the move but it needs time
It's got the groove and the gold that's mine
Is locked below the unseen deep
The more you know, the less you keep
It's holding life for my protection
The sharpest knife won't cut reflection
To see the moment to stamp the mind
to seek atonement you can not find
Is missing marks without the thought
Bright are the sparks when focus is caught
It's all the same yet still unknown
There's better aim from one's own home
