For the longest time, I couldn’t settle with the idea that Deepavali is just about shopping, new clothes, food, sweets, or temple visits.
Hinduism, the world’s oldest living science was never about blind belief. It’s a way of living aligned with cosmic mathematics and natural energies.
Every festival, ritual, and practice is deeply scientific. “As within, so without.”
🪔 Understanding Deepavali Beyond Tradition
Most celebrate it as a festival of lights.
But few know Deepavali is the most energetically powerful day of the year.
To understand why, we must look at astronomy, not mythology.
🌌 Cosmic Alignment: The First Significance
On Deepavali, something rare happens in our cosmos.
The Sun, Moon, Earth, and the central Black Hole of our galaxy align in a straight line — twice a year.
Here’s the science:
🌙 The Moon circles itself and the Earth.
🌍 The Earth circles itself and the Sun (365 days).
☀️ The Sun circles itself and the galactic black hole (≈1800 years).
During Deepavali, the alignment is:
Black Hole → Earth → New Moon → Sun
This means Earth stands first in sequence directly facing the highest vibrational energy streaming through this alignment.
Just like an antenna positioned to receive a pure cosmic frequency — Earth absorbs the full impact of the universal energy pulse.
Just like Mahashivratri, where we harness cosmic energies, Deepavali is the energetic peak of renewal and transformation.
That’s why, in ancient times, our ancestors used this window for fasting, cleansing, meditation, and oil bathing — to align the body’s energy with the cosmos.
🌬 The Shift of Cosmic Air: The Second Significance
There’s another layer of science that most have forgotten.
Every year, around Vaikasi Pournami, the breeze flows from southwest to northeast.
During Aippasi Amavasya (Deepavali), that southwest breeze stops and reverses its direction — it begins to flow from northeast to southwest.
Then, during Karthigai Pournami, the northeast breeze stabilizes fully.
If you’ve ever flown a kite around this period, you’ll feel the difference — during Deepavali until the first day of Karthigai, kites don’t fly smoothly.
That’s because the air current is in transition — the directional flow of energy is reversing.
Deepavali, therefore, marks two natural events:
- The celestial alignment (Black Hole → Sun → Moon → Earth).
- The shift in atmospheric breeze, reflecting the energy reversal in nature.
These are not mythological claims. They’re energetic observations recorded by ancient seers through thousands of years of natural attunement.
🧘♂️ The Deeper Energy Science
The macrocosm (cosmos) and microcosm (human body) mirror each other.
As the planetary energies reset, so does our inner current.
- ☀️ The Sun represents Spirit (Atman) — the source of light and consciousness.
- 🌙 The Moon represents Body (Deham) — the container of that light.
Our inner energy flows from head (New Moon) to feet (Full Moon) over 14 days.
For men, the current moves clockwise.
For women, it moves anti-clockwise.
Deepavali marks the new moon — the moment when the energy is fully withdrawn inward, into stillness and silence.
That’s why this time is used for fasting, rest, and purification. It’s the energetic reset point of the entire lunar cycle.
🔭 The Right Time to Observe Deepavali (2025)
This year, Amavasya (New Moon) begins on October 20th, 2025, at 8:25 PM (Malaysia Time).
That’s when the cosmic alignment begins — not at midnight.
Therefore:
- October 20th, 8:25 PM → Deepavali starts.
- October 21st, 5:30 AM → Brahma Muhurtham + New Moon overlap — the most auspicious time for oil bath and meditation.
🪔 The Sacred Oil Bath (Sneha Snanam)
This ritual is a cosmic recalibration — cleansing physical, mental, and energetic layers.
Use pure gingelly (sesame) oil, and apply in these 7 energy points:
1️⃣ Head
2️⃣ Armpits & thighs
3️⃣ Navel (massage clockwise)
4️⃣ Nails
5️⃣ Nostrils (1 drop)
6️⃣ Eyes (2 drops)
7️⃣ Ears (3 drops)
Leave for 30 minutes → Bathe in warm water → Feel light, clear & reborn. 🌸
🌞 What To Do
- Don’t follow the English calendar instead Tamil Solar calendar which is much more older. A new day begins after sunrise, not at midnight.
- On Oct 20, 8:25 PM, begin with prayers or meditation - this is when Deepavali starts.
- Fast or eat light after that time. Keep your body clean and calm to harness cosmic energy.
- Meditate, rest, sleep early — let your body absorb the stillness.
- On Oct 21, 5:30 AM, take your sacred oil bath (New Moon + Brahma Muhurtha).
- Avoid firecrackers — they pollute the air during nature’s purest energetic window.
🌺 The Essence
Deepavali isn’t a cultural celebration — it’s a cosmic phenomenon and a scientific opportunity for spiritual reset.
When you understand it through the lens of energy and astronomy, it becomes clear:
we are not celebrating a story — we are participating in a universal event.
When you align yourself with that awareness, every cell in your body vibrates with the frequency of the cosmos.
That is the real Festival of Lights not the lamps you light outside, but the illumination you awaken within.
