Over one thousand years ago, a small band of refugees stood on the shores of western India. They were Zoroastrians—the followers of Zarathurstra—who had fled Persia after the fall of their empire and the rise of religious persecution. Now, they had come seeking shelter in a foreign land.

When they petitioned the local ruler, King Jadi Rana, for shelter, he asked, “What are your beliefs?”

“We worship one God,” their leader replied. “We believe in good thoughts, good words, good deeds.”

“These are noble ideals,” said the king, “and not unlike our own. But my kingdom is already full. My first duty is to care for my people.”

The leader of the Zoroastrians asked for a glass, some milk, and sugar. Then, he poured the milk into the glass until it was full.

“This,” he said, pointing to the glass, “is your kingdom, and the milk, your people.

“We understand, Your Majesty, that your kingdom is full to the brim. There is no room to take more.”

He then added a spoonful of sugar and gently stirred it in.

“We will be like the sugar,” he continued. “We will not displace your people, but blend in and sweeten the whole.”

The king smiled at the wisdom in that gesture.

The Zoroastrians were granted asylum by King Rana on three conditions: they would adopt the local language, embrace some local customs, and not seek to convert others to their faith. The Zoroastrians agreed.

And so began the story of the Parsis in India, as they came to be known over time.

Through the centuries, they learned and adapted. They carried within their hearts and community the flame of their ancient faith, while outwardly serving and uplifting the land that had adopted them.

Over time, the Parsis have become one of India’s most industrious communities. They have flourished in trade, industry, and many professions. Some of India’s leading business houses —the Tatas and the Godrejs, for example—have been nobly built by Parsi families.

And they have given generously of their wealth to social causes in India, building highly respected universities, hospitals, and scientific institutions.

They sweetened the milk.

Today, in America, we are wrestling with questions about immigration. Some of us fear the loss of cultural cohesion, economic stability, or national security. Others wish to be open, generous, and faithful to our heritage as a land of immigrants.

The debate has become highly emotionally charged, leaving us with little space for the wisdom that often lies between extremes.

But the story of King Rana and the Parsis offers a bridge. It shows us what can happen when a nation welcomes immigrants, not indiscriminately, but intentionally. Not as an entitlement, but as a two-way promise.

Here are six lessons on how America can reform its immigration platform.

1. Make immigration an invitation, not an intrusion.

The Zoroastrians sought permission to enter. A healthy democracy depends on borders that are respected and processes that are trusted. 

This may seem like a hard-hearted stance to take, given the plight of those in the world who are seeking to flee rough conditions in their native lands to arrive in America and pursue the American dream. A simple experiment may help here. Would you have an “open door” policy to your home, to allow anybody who is fleeing rough conditions in their home or neighborhood to just enter and occupy a space in your home? What about your apartment building—would you want to have an “open gates” policy to your apartment building? If not, then perhaps we can start to see the logic in being mindful of not having totally open borders. 

2. Check to ensure an alignment in core values.

King Rana was fine with the Zoroastrians having their own prophet and their own scripture, but he did check for a basic alignment in worldview, and whether their faith was founded on goodness and love for all. America is founded on ideals of equality, liberty, justice, democracy, and a respect for the law. There are people and groups in the world who do not subscribe to these values. Any nation should feel comfortable welcoming immigrant prospects who do, and denying those who do not.

3. Don’t put lives in limbo.

The king asked a few questions, had a dialogue, and then made a decision. The US today has a labyrinthine legal system that, in the guise of due process, leaves families suspended in uncertainty: neither fully in nor fully out. We can do better, by creating a system that is humane, fair, efficient, and protected from legal maneuvers meant to take advantage of loopholes and processing delays.

4. We can receive with open arms, and yet within limits.

King Rana’s first concern was for his own people. A nation should be mindful of how much its vessel can hold, and of the demands that new waves of immigration would impose on its school system, housing, healthcare, social support, and more. When these resources get strained, it is at the cost of its own citizens. Perhaps the flow of immigration should be determined on the basis of what a society can gracefully absorb, and not simply by the sheer volume of aspiring immigrants that arrive at the border due to outside forces. A nation can be warm-hearted and prudent at the same time.

5. Immigrants can be guided to integrate, not isolate.

King Rana’s three conditions were not a form of cultural imposition—just a practical policy to make sure the Zoroastrians didn’t come in and create a parallel society. Perhaps the process of welcoming newcomers to any nation can involve a thoughtfully designed onboarding program that educates new immigrants on language and social norms, and inspires them to embrace the nation’s core ideals and identity. People should be able to retain their roots while rising into the nation’s shared values.

6. Over time, immigrants become the lifeblood of a nation.

The Parsis did not become a burden. They became builders, creators, givers. They elevated their new home. At its best, America has been like King Rana—able to see not just who a person is, but who they might become if given the chance. And often, the immigrants who call America home—our scientists, farmers, teachers, soldiers, entrepreneurs, nurses—have come like the Parsis, not just to dwell here but to sweeten the milk.

It is time we moved beyond the false choice between chaos and callousness. We need to come together to build an immigration framework that is anchored in dignity, discernment, and shared responsibility.

The story of the Parsis is not just a history. It is a model. A mirror. And a map forward.

If we can find in our hearts the courage to act with conviction and compassion, then perhaps, one day, future generations will speak of how America was just like that ancient king. Wise enough to make space for sweetness, without spilling the milk.
