My father died recently (at 94 y/o) and that is what I kept whispering to him as he lay dying.
And to feel free to let go...that I would take care of things so that he shouldn't worry.
That poem means a lot to me.
A great poem, at certain times, can have real emotional power. The Thomas poem is one such. Another one is e e cummings' poem "My Father Moved Through Dooms Of Love." It too was written for the poet's father, and e e cummings always considered it to be his best poem (out of hundreds of great works). It's my favorite of his too.
It's a little on the artsy side, but it's a great tribute to the most remarkable and heroic men in our lives -- our fathers.
Sad to say, they don't make poems like these anymore.
I urge you to check it out. (But I've warned you: it's a bit artsy!) :^)
