Performing the Kedareswara Nomu or Vratham involves the following steps:

1. Preparation: Cleanse yourself by taking a bath and wear clean, traditional attire. Choose a designated space for the vratham, preferably near a Shiva temple or an altar with a picture or idol of Lord Shiva.

2. Fasting: Observe a fast for the designated period of the vratham. This may involve abstaining from certain food items or following a strict vegetarian diet. Consume simple and sattvic (pure) meals during this time.

3. Daily Rituals: Engage in daily prayers and rituals dedicated to Lord Shiva. Recite Shiva mantras, such as the "Om Namah Shivaya" mantra or other stotras (hymns), expressing devotion and seeking the blessings of Lord Shiva. Offer flowers, incense, and water to the deity.

4. Austerity and Discipline: Practice various forms of austerity and discipline during the vratham. This may include waking up early, taking cold baths, avoiding worldly distractions, and focusing on spiritual pursuits. Reflect on the divine qualities of Lord Shiva and seek to imbibe them in your life.

5. Visit Shiva Temples (optional): If possible, visit Shiva temples during the vratham period to offer prayers and seek the blessings of Lord Shiva. Participate in special rituals or ceremonies conducted in the temple.

6. Conclusion: At the end of the vratham period, perform a special concluding ceremony. Express gratitude to Lord Shiva for his blessings and seek his continued guidance and protection. Offer prayers, perform rituals, and make offerings to Lord Shiva as a sign of devotion and thankfulness.

It is recommended to consult with a priest or individuals familiar with the specific customs and practices of the Kedareswara Nomu or Vratham to receive accurate guidance and instructions tailored to your cultural and religious traditions.
