"Happy Maha Shivaratri" in Nepali is said as "महाशिवरात्रिको शुभकामना!" or with the sacred mantra "ॐ नमः शिवाय!" (Om Namah Shivaaya!) and the exclamation "हर हर महादेव!" (Har Har Mahadev!).

To wish blessings, say "भगवान् शिवले तपाईंलाई शान्ति र समृद्धि प्रदान गर्नुहोस्!" — "May Lord Shiva bless you with peace and prosperity!"

Maha Shivaratri falls on Krishna Chaturdashi of Phalgun — typically late February or early March. It is a public holiday in Nepal, with the central celebrations at Pashupatinath Temple where hundreds of thousands gather.

The night is spent in prayer, fasting, and vigil (jagaran). Devotees perform four rounds of worship through the night, each dedicated to a different aspect of Shiva.

Pashupatinath Temple is one of the most sacred Shaiva temples in the world and a UNESCO World Heritage Site. On Shivaratri, hundreds of thousands of devotees and sadhus from across Nepal and India converge on its ghats, creating an extraordinary atmosphere of devotion.

The temple remains open through the night for Rudra Abhishek — the sacred bathing of the Shivalinga with holy water, milk, and honey — performed by Bhatt priests, making Shivaratri at Pashupatinath one of South Asia's most striking spiritual spectacles.

Fasting (vrat) on Maha Shivaratri is observed as an act of devotion and self-purification in preparation for worshipping Lord Shiva. According to Hindu tradition, fasting on this night is believed to please Lord Shiva and result in the fulfillment of sincere prayers, purification of karma, and spiritual merit.

The key rituals of Maha Shivaratri include: Abhishek (bathing the Shivalinga with sacred substances including water, milk, curd, ghee, honey, and sugarcane juice); offering bilva (bael) leaves which are particularly sacred to Shiva; lighting diyas (oil lamps); and chanting Om Namah Shivaya and other Shiva mantras throughout the night.

Devotees also observe a night-long vigil (jagaran), staying awake in prayer and meditation, as it is believed that sleeping on Shivaratri night is inauspicious. Many visit temples four times during the night to perform four rounds of worship. The fast is broken the next morning after bathing and final prayers to Lord Shiva.

Om Namah Shivaya (ॐ नमः शिवाय) is one of the most sacred mantras in Hinduism, specifically in the Shaiva tradition. It translates roughly as "I bow to Shiva" or "I offer my reverence to Lord Shiva." The mantra contains five syllables (Na, Ma, Shi, Va, Ya) that correspond to the five elements: earth, water, fire, air, and space.

The mantra is considered a direct invocation of Lord Shiva's presence and grace. Chanting it on Maha Shivaratri is believed to be especially powerful because the divine energy of Shiva is said to be most accessible on this sacred night. Devotees chant it continuously throughout the night as a form of meditation and devotional offering.

In Nepal, "Om Namah Shivaya" is the most commonly heard mantra at Pashupatinath Temple, especially during Shivaratri. It is considered both a prayer and a meditation practice: regular chanting is believed to purify the mind, reduce ego, and draw one closer to the divine consciousness that Shiva represents.
