Inscription For A Gravestone

My family are about to put in place a gravestone for my late father. His favourite poem was Lake Isle of Innisfree by W. B. Yeats. I was hoping to have a line from the poem inscribed on the gravestone. I was thinking of using "And I shall have some peace there, for peace comes dropping slow". As poetry isn't a strong point of mine, I was hoping to hear some thoughts from people with a better knowledge. Do you think this is fitting for a gravestone? Is it out of place without the line that follows it, "Dropping from the veils of the morning to where the cricket sings"? The line to me brings to mind an abundance of peace and rest.

I'd appreciate people's thoughts on this, and I'm sorry if I've posted this in the wrong place. Thank you.

Here's a link to the poem: http://www.poets.org/poetsorg/poem/lake-isle-innisfree

I like these two lines, but I am no expert on these matters.

I will arise and go now, for always night and day
I hear lake water lapping with low sounds by the shore;

Two lines might be too long. Perhaps just "I will arise and go now".
