Sarva Pitru Amavasya, also known as Mahalaya Amavasya, is a day full of beautiful skies, ancestral stories, and heritage. It is also a night when the darkness on Earth reflects the echoes of our souls.

Sarvapitri Amavasya is a term that comes from three Sanskrit words: “Sarva,” meaning “all” or “complete”; “Pitri” or “Pitru,” which refers to our ancestors or forefathers; and “Amavasya,” the day of the new moon. The phrase represents a special day of the new moon, a moment for families to come together to remember, honor, and perform rituals for the souls of their ancestors.

This festival, for those in the West who are curious, is closely linked to the moon’s cycles, the arrangement of the stars, and the profound ties that exist between the living and their ancestors. Yet, beneath the rituals, there lies a profound contemplation of our lives and the universe, where light and dark are not just events but carry with them memories, gratitude, and hope.

The significance of amavasya (new moon sky) and purnima (full moon sky).

Amavasya and Purnima are significant not only in spiritual practices but also in the fascinating world of astronomy. During Purnima, the moon shines brightly, fully visible to us, while on Amavasya, it retreats from sight, completely hidden from view. The Earth’s spin and its journey around the Sun and Moon create these beautiful phases. The Hindu calendar is unique compared to the Gregorian calendar because its months and festivals are determined by the moon’s phases.

For thousands of years, ancient Indians watched the skies shift, mapping not only the cosmos but also the profound cycles of life and death. Each month, the moon gracefully rises and falls, painting the sky and acting as a common timekeeper for farmers, sailors, and dreamers all around.

Indian custom sees Purnima and Amavasya as the cosmic walls of time, representing both the end of things and the start of new ones. People often see the full moon (Purnima) as a time of plenty and spiritual satisfaction. On the other hand, the new moon (Amavasya) tells us to think, remember, and focus on ourselves.

The way geography influences our perspective of the skies from every part of the subcontinent deeply intertwines with the essence of religious life.

What is Sarva Pitri Amavasya, and why do Indians celebrate it?

Sarvapitri Amavasya signifies the dark skies that arrive at the close of the final day of Pitru Paksha, a significant 16-day lunar period. In this time, Hindus honor and remember their ancestors.

On September 21, 2025, this important event will happen. It will start in the early morning and last until the next morning.

Families all over India come together on special nights to honor their ancestors by doing shraddh, giving them food and water, and taking a moment to think about the generations that came before them and ask for their blessings and, maybe, their forgiveness.

Yet, the last Amavasya serves as a moment to pay tribute to all our ancestors, particularly those whose death anniversaries might have faded from our memories or remain unknown. The rituals act as a sincere plea and a warm blessing, holding onto the memories until the next year arrives.

The significance of the 16-day lunar cycle.

Pitru Paksha is a period that unfolds from the full moon to the new moon, mirroring the moon’s soft disappearance from the sky. This waning phase signifies a soft departure of ancestral energies, highlighting their journey from our earthly lives to more delicate realms. Starting with the bright glow of Purnima, each night slowly transitions into darkness, reflecting how each generation softly fades into history, leaving us with treasured memories and deep appreciation on Sarvapitri Amavasya.

This fortnight isn’t merely a chance occurrence; it stems from a profound awareness of the connection between the material and spiritual worlds. In Hindu tradition, it is thought that the souls of those who have departed stay close to the earth during this time, kindly accepting offerings and bestowing gentle blessings.

During this time, we do things like offer drinks, say prayers, and share meals. These rituals help those who have passed away feel better and bring us who are still alive closer together.

Why does Sarvapitri Amavasya come before the Durga festival?

The explanation lies in India’s diverse seasonal and cosmic terrain. Amavasya marks the end of ancestral rites and prepares for Devi Durga, the mother goddess, to arrive with the Shukla Paksha (the waxing moon).

This moment bridges the conclusion of one chapter and the start of another, transitioning from darkness to light. Families pay tribute to their ancestors as they welcome the goddess, whose presence brings victory, new beginnings, and a sense of balance in the world.

Navratri and Ghatsthapana, marked by the moon’s return to fullness, transform the mood from reflection to one filled with joyful celebration. After reflecting on our shared history, it seems we can now embrace the new energy that the mother goddess brings into our lives.

Is there anything in the West that resembles Sarvapitri Amavasya?

The answer is no, but they do believe in honoring and remembering their ancestors in a different way.

In ancient Western societies, individuals made it a point to pay tribute to those who had departed from this world. We can see this in traditions like the Greek Anthesteria, the Roman Parentalia, and the observances of All Souls’ Day and Halloween in Christian Europe. These festivals, tied to the shifting seasons and lunar cycles, represented a time when the line between worlds softened, creating an opportunity for the living to reach out to their cherished ones who had departed.

Over time, many traditions have evolved from direct appeasement rituals to symbolic remembrance gestures like prayers, grave visits, and candle lighting in church windows. The West no longer believes that the dead can return to family gatherings or bestow blessings, allowing for more thoughtful ways to honor them.

These are all beliefs, and we should honor them even if we don’t follow that culture.

Can our ancestors come back as animals or birds?

On this special night, it’s believed that our ancestors, having left their earthly forms behind, are more inclined to return and reconnect with those they hold dear. People often view them as birds and sometimes various other animals.

Crows and other animals are fed on Sarvapitri Amavasya as more than just a symbolic act. This comes from the belief that Lord Yama, the god of death, lets ancestors appear as birds.

A crow cawing at your door today signals that your offering has been recognized. These rituals foster a dialogue that bridges various realms, linking our visible world with the mysteries that exist beyond in a timeless understanding. This idea resonates with our common experience that memory, love, and gratitude go beyond the limits of time and our physical lives.

What if our ancestors’ souls still haven’t traversed to the other dimension?

Mythology suggests that leaving the world does not imply disappearing, but rather the start of a gentle journey that continues on.

On Sarvapitri Amavasya, rituals bring comfort to souls by giving them peace (moksha) or at least spiritual food as they make their way through the afterlife.

If we overlook or disregard them, it’s believed that our ancestors may linger with us, caught between realms, withholding their blessings from those of us who are still here. With the right rituals and care, these spirits can become kind protectors—ancestral energies that offer their wisdom, warn us of dangers, and empower the living with strength.

Final thoughts.

The West sees India’s distinct landscape and mythology, as well as the common human experience of remembering, healing, and hope that the individuals we’ve lost still affect the world. It gently reminds us that night, memory, grief, and love are interconnected, like the moon’s impact on the tides.
