Two observances define Karthika Masam 2026 above all others: Karthika Snanam — the holy pre-dawn bath — and Deepa Daanam, the offering of lamps. Together they make the whole month one continuous act of purification and light.

Karthika Snanam — The Holy Bath

Through Karthika, devotees bathe before sunrise in a river, temple tank, or at home with a sankalpam dedicated to Shiva and Vishnu. The cold pre-dawn bath is said to wash away accumulated sins and grant the merit of pilgrimage. Many follow it with a temple visit and the day’s first lamp.

Deepa Daanam — The Offering of Lamps

Lighting and donating lamps is the heart of Karthika. Devotees light ghee or sesame-oil lamps at home, under the Tulasi and Amla trees, at temples and on riverbanks; float lamps on water; and hoist the Akasha Deepam — a sky-lamp on a tall pole — for the whole month. A single lamp lit in Karthika is said to dispel the darkness of many lifetimes.

How to Observe

  1. Rise before dawn; take the Karthika Snanam with a sankalpam (river/tank where possible, else at home).
  2. Light a lamp at the Tulasi and at your altar each morning and evening.
  3. On Mondays and Pournami, light extra lamps and visit a Shiva or Vishnu temple for deepa daanam.
  4. Hoist an Akasha Deepam for the month, and float lamps on Pournami where tradition allows.

Mantra

Shiva: ॐ नमः शिवाय · oṃ namaḥ śivāya. Vishnu: ॐ नमो भगवते वासुदेवाय · oṃ namo bhagavate vāsudevāya.

How the Diaspora Observes

Where rivers are far, the diaspora across the USA, UK, Canada, Australia, the UAE and Germany takes a symbolic Karthika Snanam at home and lights daily lamps (smokeless/LED indoors where needed); temples hold Karthika Deepotsavam with rows of lamps and group deepa daanam.
