The Irish blessing "May your blessings outnumber the Shamrocks that grow" is a beautiful and popular saying that is often used by Irish people and those who appreciate Irish culture. It is believed to come from the ancient Gaelic tradition of blessing people and wishing them well.

The old Irish blessing reads: 

"May your blessings outnumber
The shamrocks that grow,
And may trouble avoid you
Wherever you go."

The shamrock is a symbol of Ireland and is said to represent the Holy Trinity. It is a small, three-leaved plant that grows abundantly in Ireland and is often used as a symbol of good luck and prosperity. The blessing wishes that the recipient will be blessed with good fortune and success that will be as plentiful as the shamrocks that grow.

The second part of the blessing, "may trouble avoid you wherever you go," is a wish for the recipient to be protected from harm and misfortune. It is a way of expressing the hope that the person will have a peaceful and happy life, free from troubles and worries.

Irish people use these kinds of blessings in many different ways. They may be spoken as part of a greeting, a farewell, or as a way of wishing someone well for a particular occasion such as a wedding, birthday or other milestones. The blessings are often seen as a way of expressing the warm and generous nature of the Irish people, who are known for their hospitality and kindness.

The popularity of Irish blessings has grown around the world, with many people from different cultures and backgrounds adopting them as a way of expressing their appreciation for the beauty and wisdom of Irish culture. The blessings have been included in books of poetry, greeting cards, and even on social media, where they are shared and liked by millions of people.

One reason for the enduring popularity of Irish blessings is that they speak to universal human desires for happiness, health, and good fortune. They offer a reminder that these things are possible, and that they can be wished for and shared with others.

The Irish blessing "May your blessings outnumber the shamrocks that grow and may trouble avoid you wherever you go" is a beautiful and meaningful expression of the hope for good fortune and happiness. It reflects the generous and warm-hearted nature of the Irish people and has become an enduring symbol of the beauty and wisdom of Irish culture around the world.
