Most of the greatest poets were not recognized for their work until they had long been laid to rest. As we know, a poem is the spontaneous overflow of powerful feelings, wherein thoughts flow freely like a river.
Love poems have existed since ancient times. There are hundreds of poems on the Internet that are dedicated to mothers and Mother's Day. Simple and soothing words acknowledging a loss, accompanied by a meaningful sympathy or condolence poem can touch a heart like nothing else can.
There are dozens of poets who have written poems specifically for an anniversary. Once you are absolutely sure what you want to say with the love poem you select, you should decide whose poetry best represents your feelings. A poem for the deceased that prompts that thought is invaluable after a loved one has died.
Select a main theme for the Poem and start writing. This is a fun way to get everybody in the mood to celebrate.
