Take a bath in the evening before puja. Wear clean white or light-colored clothes. Maintain a sattvic and devotional mindset throughout the day.

Sit before the Shiva Linga or image. Hold water in the right palm and formally resolve to observe the Somvar Vrat. State your name, gotra, and purpose.

Pour milk slowly over the Shiva Linga while chanting "Om Namah Shivaya." Follow with clean water. The stream should be continuous and gentle.

Offer bilva leaves (smooth side up) and white flowers on the Shiva Linga. Light dhoop/incense and the ghee lamp. Circumambulate the Linga three times if possible.

Chant "Om Namah Shivaya" 108 times using a Rudraksha mala or counting on fingers. Sit quietly with eyes closed, focused on Lord Shiva in your heart.

Perform aarti with a ghee lamp, circling clockwise before the Shiva Linga. Offer fruits as naivedya. Conclude with sashtanga namaskar (full prostration) and pray for Shiva's blessings.
