Grief, Quantum Physics and Eternal Spirit

The following message is adapted from a deeply personal letter I wrote to my daughter-in-law in response to the eulogy she delivered at the memorial service for our only child, who passed away from cancer. Although I could not attend due to hospitalization, I was deeply moved by her words and felt compelled to record my own thoughts—rooted in personal grief and lifelong philosophical reflection. My aim was not only to share them with her but also with the wider community, hoping they might resonate with others who have endured loss.

This expression weaves together faith-based beliefs from many traditions and science-based understandings of the cosmos, particularly through the lens of quantum physics, as I have come to know from popular science readings, my background in philosophy and clinical psychology, decades of professional practice, and personal spiritual reflections enriched by poets and thinkers.

“…While standing beside my son’s grave, memories flooding in, I feel my body vibrate with his presence—as quantum entanglement suggests, linked at the micro-electrical levels of our existence—a connection deepened through our lived experiences together. Just as entangled particles reflect each other’s state instantly across distance, I believe that deep emotional and spiritual bonds endure beyond physical separation. Love, shared experiences, and presence form invisible threads—quantum echoes of eternal connection—mirroring spiritual beliefs in unity within the realm of the One.

This idea—of love and presence transcending form—appears in the poetry of Rabindranath Tagore, Nobel laureate and philosopher-poet of Bengal. As a child, I came to love and memorize his poems, and I often listen to his songs while driving. In Jokhon Porbe Na Mor Payer Chinho Ei Bate (“When My Footprints No Longer Mark This Path”), he writes:

When my footprints will no longer mark this path, I will have left behind name and form and gone afar— Yet I shall return again and again, in new names, In fresh forms—carrying the same eternal self.

Rumi, the 13th-century Persian Sufi mystic, whose work I came to appreciate more deeply through my association with your Azeri Iranian father, affirms:

“Don’t grieve. Anything you lose comes round in another form.” “Goodbyes are only for those who love with their eyes. For those who love with heart and soul, there is no separation.”

My wife, our son’s beloved Filipino mother, finds solace in her Catholic faith and its promise of eternal life.

My father, A.A.F. Mohi, who lived in the Indian subcontinent, offered a Muslim Quranic perspective in his poem Life and Death:

“…Man must die, Await the inevitable moment, With only consolation in spirit… Verily to God we belong, And to Him we return.”

Such beliefs resonate with the Hindu concept of moksha, the Christian hope of resurrection, and the Buddhist understanding of nirvana—the ultimate release from human wants and suffering, and the merging of the soul with the One Ultimate Reality.

The popular Irish ballad “Danny Boy,” which I often listen to—and which your late beloved Irish American mother must have loved—echoes this timeless connection:

“But come ye back when summers in the meadow, Or when the valley’s hushed and white with snow… ’Tis I’ll be here in sunshine or in shadow…”Across spiritual traditions, there is this shared belief in an enduring, all-pervading consciousness—from which all life emerges and to which it ultimately returns.

Whether expressed as the Atman–Brahman unity of Vedanta, the Spiritus Mundi of mystical Christianity, Tawhid in Islam, or Ein Sof in Kabbalistic Judaism, the message is the same:

The soul belongs to a greater, eternal Reality of the One, present both within us and all around us. This truth finds echo in the gift hanging I saw on your door the other day—a sign that reads, “Hush, listen carefully, I am around, ” a reminder of our son’s continuing presence.

Remembering Dostoevsky: on the Eve of My Brother’s Death and Our Human Longing for Eternal Connection

..That night, some 25 years ago, as we said goodnight, my brother appeared frightened and anxious. My eldest sister began to pray. One of us—I no longer remember who—spoke softly about not being afraid of whatever lay ahead, about how we would all be together again someday, reunited with those living and those gone. These thoughts were spoken aloud, almost in unison, as if we were reassuring not only him, but ourselves.

At that moment, the final pages of The Brothers Karamazov came vividly to mind.

The children, mourning the death of their young friend, ask Alyosha: “Can it be true, as they teach us, that we shall all rise again from the dead and shall live and see each other again, all of us?”

To which Alyosha replies: “Certainly, we shall all rise again, certainly we shall see each other, and shall tell each other with joy and gladness all that has happened.”

What we were saying that night echoed this passage almost word for word—that we would surely see each other again and be together someday in another world. Though my brother and I were not people of prayer, we joined in emotionally and sincerely, repeating what my deeply religious sister uttered. I saw a faint smile, a sense of peace, settle on my brother’s face.

In that moment, I experienced a profound sense of unity—not only with those in the room, but with all who were dear to me: friends and “kind strangers,” loved ones and admired figures no longer alive. It felt as if all were momentarily gathered in a shared affirmation. I sensed an eerie yet deeply comforting connection to Dostoevsky’s ending—a confirmation that human beings, across cultures and centuries, return to the same hope when facing the final mystery….”

Relativity of Time

Some physicists suggest that time itself is not absolute but relational—what we call the “past” may still exist in another form of “now.” Einstein once wrote to the widow of his close friend, Michele Besso, that the distinction between past, present, and future is only a “stubbornly persistent illusion.” In quantum theory, a particle can exist in two states at once, hinting at a multiverse where past, present, and future coexist.

Whether expressed through physics, poetry, religion, or philosophy, one truth endures: love is not limited by time. Our son’s kindness, laughter, and devotion are not lost. His presence—and the memories of all our loved ones—live within us, resonating across both the quantum realm of physical reality and the Eternal Spirit within the Reality of One.

In conclusion, reading the eulogy of my daughter-in-law echoed the depth of our shared grief and enduring love, reminding us of the “eternal connection” that binds us all. We draw strength from our memories, from one another, and from the many ways our son—beloved husband, devoted father, cherished family member, loyal friend, and valued presence—lives on: within time, beyond form, and always in spirit, as do the loved ones and all those with whom we formed meaningful connections in our lived experience.
