🌸 Onam (Thiruvonam) Vrat Katha
The story
The asura king Mahabali, grandson of Prahlada, was generous, just and a devotee of Vishnu; in his kingdom all were equal and happy — the gods feared in envy that Bali would take Indra's throne; at Aditi's prayer Vishnu came as Vamana (a young Brahmin) to Bali's Ashwamedha yajna and asked for three paces of land; his guru Shukracharya stopped him, but Bali gave the gift — Vamana in his cosmic form measured earth and heaven in two paces, and for the third Bali offered his head; Vishnu made him king of the netherworld (Sutala) and granted the boon — 'you will come one day a year to meet your people' — that is Thiruvonam; in Kerala the festival begins from Thrikkakara (the temple of Vamana).
Onam is the memory of Kerala's 'golden age' — in the reign of Maveli (Mahabali) 'no theft, no deceit, no lies, no sorrow; all equal' (the Onam song); hence on Onam every home is decorated, every family in new clothes, everyone's stomach full — so that the returning king sees his people happy; celebrated by all without distinction of caste or creed.
The tale of vallam kali: at the Parthasarathy (Krishna) temple of Aranmula a devotee Brahmin's Thiruvonam feast (the Thiruvona sadya) was carried to Krishna by boat — since then the Aranmula vallam kali on Uthrattathi (the palliyodams — snake boats, the vanchipattu songs); pulikali since the time of Maharaja Sakthan Thampuran of Thrissur (200 years) — dancers in tiger paint, on the fourth Onam.
Why this katha — the significance
The tale of Mahabali and Vamana (below): Vishnu as Vamana took the three worlds from Bali in three paces, sent Bali to the netherworld but granted him the boon of visiting his people once a year — that day is Thiruvonam; Onam is the memory of that 'golden age' (Maveli Nadu — when all were equal, no theft, no lies) — the Onam song 'Maveli nadu vaneedum kalam…'.
The ten days: Atham (1 — the first row of petals of the pookalam, the festival begins from the Thrikkakara temple), Chithira, Chodhi, Vishakam, Anizham, Thriketa, Moolam (the sadya begins), Pooradam (the Onathappan idols), Uthradam (the first Onam — 'Uthradappachil', the rush of shopping), Thiruvonam (the main — the second Onam), Avittam (the third), Chathayam (the fourth — the immersion of Onathappan); the festival runs 12 days from Atham to Chathayam.
A harvest festival too — the celebration of plenty after the paddy harvest in Chingam, the end of the monsoon; celebrated by people of all faiths (Kerala's shared festival); the Kerala government's week-long celebration (the procession and 'Onam Week' in Thiruvananthapuram), the Aranmula vallam kali (Uthrattathi), Vaikom Ashtami separately.
How the katha is heard
- Hear or read the katha after the puja, before the aarti — the whole family sits together.
- The one keeping the vrat should listen with a calm mind; keep a lamp lit and a little akshat-flowers in hand.
- At the end, offer the flowers at the deity's feet and bow; share the prasad with everyone.

Frequently asked questions
When is Onam (Thiruvonam) in {Y}?
This year's Thiruvonam date is above — the day of the Shravana nakshatra in Chingam (the solar Simha month) (by the sunrise nakshatra); Atham (the start of the pookalam) 9 days earlier, Uthradam a day earlier, Avittam-Chathayam two days later; the Kerala government's calendar (the Malayalam calendar) gives the same day — if the nakshatra spans two days, follow the Kerala panchang's date.
Whose festival is Onam — Hindu or everyone's?
The root tale is of Vamana and Mahabali (Vaishnava), but in Kerala Onam is a secular harvest and state festival — Hindus, Christians and Muslims all celebrate with pookalam, sadya and Onakkodi; a public holiday and 'Onam Week'; hence it is called Kerala's 'national festival'.
How to make the pookalam, which flower on which day?
On Atham a single row of only Tulsi and thumba (white) on a round base of cow dung/clay; from Chithira one colour/row daily — yellow (marigold), orange, red (chembarathi-chethi), purple (kakka poovu), green leaves; 10 rows on Thiruvonam, with the lamp and Onathappan in the centre; by tradition the petals are changed daily; paper/rice rangoli as an alternative outside Kerala.
How many dishes in the Onasadya and in what order?
Traditionally 26 (20-64 in places): pappadam-banana-chips-pickles (left), kichadi-pachadi-thoran-olan-avial-koottukari-erissery-kalan (top), on the rice parippu-ghee → sambar → rasam → moru, finally 2-3 payasams; the tip of the leaf to the left, only on a banana leaf; 8-10 at home is a sadya too — the spirit is of completeness.
What is Onathappan/Thrikkakara Appan?
Square pyramid-shaped clay idols (3-5) placed in the centre of the pookalam from Pooradam to Thiruvonam — the symbol of Vamana/Mahabali/the deity of the Thrikkakara temple; decorated with rice-flour paste, offered ada and flowers; immersed on Chathayam; Thrikkakara (Kochi) is the temple of Vamana — the origin of Onam.
How to celebrate Onam outside Kerala?
A small pookalam (flowers/paper), Onathappan (clay/brass), the morning lamp puja, kasavu/new clothes, a sadya of 8-10 dishes on a banana leaf (or a plate), payasam, the family feast, Onam songs/Thiruvathira, pranam to the elders in Kerala on video; go to the community sadya of your city's Malayali samajam — non-Malayalis are warmly welcome too.
