Things Not to Do on Amavasya Day: Amavasya, the new moon day, holds immense spiritual significance in Hindu tradition. It marks the end of the lunar cycle, a time when the moon is completely invisible from Earth. Far from being just a celestial event, Amavasya is deeply tied to energy, rituals, and ancestral connections.
While some may perceive it as inauspicious, it is more accurately described as a day of stillness, silence, and spiritual reflection. But what exactly should you avoid doing on this powerful day—and what should you embrace instead? Let’s explore everything in detail.
Things Not to Do on Amavasya Day
On Amavasya, the focus is inward. It’s not a day for material or celebratory activity. Here are things traditionally avoided:
❌ Starting New Projects or Business Ventures
Avoid beginning new tasks, signing contracts, or initiating major work. It is believed that new moon days lack the energetic support for growth and expansion.
❌ Weddings, Housewarming, or Naming Ceremonies
Since Amavasya is associated with low energy and ancestral remembrance, celebratory rituals are considered inauspicious.
❌ Long-Distance Travel
Traditionally, travel is discouraged on this day due to the unstable lunar energy. Many believe it can lead to obstacles or delays.
❌ Cutting Hair or Nails
This is tied to purity. Cutting hair or nails on Amavasya is said to interfere with spiritual focus and ancestral rituals.
❌ Consuming Non-Vegetarian Food or Alcohol
These foods are considered tamasic (heavy and dulling to the senses). A sattvic (pure and light) diet is recommended instead.
❌ Negative Thoughts, Arguments, or Anger
Emotional stability is key. The moon governs the mind, and on Amavasya, mental restlessness can peak. Avoid heated conversations or emotional turmoil.
❌ Sleeping During Sunset
Evening hours are ideal for lighting lamps and connecting with ancestral energies. Sleeping during this time is believed to disrupt the spiritual benefits of the day.
❌ Visiting Cemeteries or Isolated Places
Many believe the veil between the physical and spiritual realms is thinner on Amavasya. It’s best to avoid spiritually dense or eerie places.

Things to Do on Amavasya Day
Now that you know what to avoid, here’s how to positively align with Amavasya’s spiritual energy:
✅ Offer Pitru Tarpan (Ancestral Prayers)
Amavasya is the most powerful time to honour your ancestors. Offer water mixed with black sesame seeds and pray for their peace.
✅ Light a Diya in the Evening
Lighting a lamp at home or under a Peepal tree symbolises the dispelling of darkness, both physical and spiritual.
✅ Donate to the Needy
Acts of charity on Amavasya are considered highly meritorious. Offer food, clothes, or money to the poor or animals.
✅ Meditate and Practise Silence
Spiritual silence (maun) enhances inner clarity. If possible, avoid unnecessary speech or distractions.
✅ Chant Mantras and Read Scriptures
Reciting “Om Namah Shivaya” or the “Maha Mrityunjaya Mantra” is believed to bring peace and protection.
✅ Eat Light, Sattvic Food or Fast
Keep your diet pure. If you can, observe a fast (details below). Avoid onion, garlic, and heavy meals.
✅ Take a Holy Bath Early Morning
Bathing in sacred rivers or with a few drops of Ganga water purifies both body and mind.
Is Amavasya Considered a Good Day?
From a spiritual standpoint—yes. While it’s not ideal for material beginnings, Amavasya is excellent for:
- Connecting with your ancestors
- Performing spiritual practices
- Releasing negative patterns
- Resetting your energy
In fact, special Amavasya days like Mahalaya Amavasya or Mauni Amavasya are deeply revered and draw millions of devotees for ritual bathing, fasting, and ancestral prayers.
Why Are There Restrictions on Amavasya Day?
Amavasya, the new moon, signifies a time of transition—a moment when lunar light disappears from the sky. In Vedic tradition, the moon is said to govern the mind. Its absence can influence our emotional state, leading to increased mental restlessness, fatigue, or even spiritual vulnerability.

Ancient seers were deeply attuned to these cosmic shifts. They recognised that Amavasya carries low lunar energy, making it a day best suited for introspection, not outward action. Rather than fear, the restrictions observed are a form of energetic hygiene, encouraging silence, simplicity, and stillness.
Moreover, Amavasya is believed to be the time when ancestral energies are closest to Earth. This is why it’s dedicated to Pitru Tarpan—a ritual of remembrance and gratitude for our forebears. Avoiding worldly distractions ensures a clearer space for these offerings, helping us honour our lineage with full presence and respect.

Scientific Perspective on Amavasya Beliefs
You don’t have to be religious to appreciate the logic behind Amavasya rituals. Science, too, acknowledges the influence of lunar cycles:
- The new moon significantly impacts ocean tides, and since our bodies are 70% water, it’s plausible that it affects us too
- Studies have shown that moon phases can influence sleep patterns, mood swings, and emotional fluctuations
- Ancient agrarian societies aligned their crop cycles, rituals, and spiritual practices with the moon, demonstrating an advanced understanding of nature’s subtle rhythms
In essence, many Amavasya beliefs mirror natural laws and biological responses. These aren’t outdated superstitions, but time-tested practices based on observation and reverence for universal cycles.
