When to Light What — The Moment Guide
Twenty-four moments across the ritual year, each with the correct diya, the correct fuel, the correct wick, and the correct duration. This chapter is the map.
Light a diya at four daily moments: pre-dawn Brahma Muhurta (for serious practitioners), morning aarti (sunrise, the essential minimum), evening sandhya (30-60 minutes after sunset, the most auspicious Lakshmi moment), and before sleep. A diya at the main entrance at dusk invites Lakshmi.

The previous chapters have opened the components: why the flame (Ch 1), how to read it (Ch 2), the diya as object (Ch 3), the fuel (Ch 4), the wick (Ch 5), single vs multi-wick (Ch 6), akhand (Ch 7), samai (Ch 8), Diwali (Ch 9). All of this is vocabulary. This chapter is the map — the specific mapping of household ritual moments to the correct diya, fuel, and duration for each.
Volumes 1, 2, 3, and 4 each closed with a moment guide — a matrix that mapped every household ritual moment to its correct form of smoke, fragrance, samagri, and mala. This chapter is the fifth companion. Every ritual moment mapped to its correct flame practice.

Twenty-four moments. Every one mapped. This is the household flame playbook for the full ritual year.
“A single flame is the daily foundation. Panchamukhi arrives for the elements' presence. Akhand arrives for Navratri and the deepest vows. Samai arrives for South Indian daily and Karthigai. Diwali multiplies flame beyond count. Each moment in the year has its correct flame — and the household that maps them has the tradition's complete flame practice.”
