Lhabab Duchen

What it is

Lhabab Duchen is one of four great festivals in the Buddhist year, each tied to an event in the life of Gautama Buddha. This one looks to the day he left the gods' realm and came back to live among people. Its Tibetan name carries the sense of a divine descent at a great time. The date is set by the Tibetan lunar calendar, on the 22nd day of the ninth month, so it moves each year against the Western calendar. Dates listed for recent years fall between late October and mid November.

The story told

According to the accounts in the source, the Buddha was 45 when he rose to teach his mother, Mayadevi, who had been reborn in the gods' realm, Indra's heaven, also called the Heaven of the Thirty-Three. He stayed three months, teaching without a break, both to repay her kindness and to help the gods there. The Kangyur describes his seat as a shining white stone in a fine grove of trees. His mother is said to have reached arhatship there.

The return to earth

When his disciple Maudgalyayana asked him to come back, the Buddha debated the matter under a full moon before agreeing. A week later he came down a triple ladder that the gods Indra and Brahma had made, among rainbows and a crowd of celestial beings. Other sources credit Viswakarma, the god of machines, with building it. He landed at Sankassa, in India, a place counted among the eight great sites of his life. The Mahamaya Sutra says King Prasenajit and the Buddha's community of monks were waiting there for him.

Merit on the day

Tibetan Buddhist teaching gives this day unusual weight. The article says good deeds and bad ones are multiplied ten million times over, while a note in the same source gives the figure as a hundred million. For practitioners the exact number matters less than the point: prayer, giving and other virtuous acts are believed to count for far more than on an ordinary day. The day stands among a set of four great Buddhist festivals, each recalling an event in the Buddha's life.

Related observances

The same event is kept under other names in several countries, each on its own lunar date. In Sri Lanka it corresponds to Vap Full Moon Poya. In Myanmar the related day is the Thadingyut Festival. In Thailand it is Tak Bat Devo, and in Laos Boun Suang Huea. The source also points to Abhidhamma Day as a related observance. In all these places the celebration follows local calendars rather than the Tibetan one, though the story behind the day is the same.

How Lhabab Duchen is kept

Tibetan Buddhists mark Lhabab Duchen with prayer and virtuous acts rather than with a large public feast. The day is one of four great festivals in the Buddhist year. His mother Mayadevi is remembered as having reached arhatship, the state of a fully awakened disciple, after hearing his teaching in the gods' realm. In Sri Lanka, Myanmar, Thailand and Laos the same event is kept on local lunar days under other names, so the Tibetan date and the local one can fall apart.

When and where

Lhabab Duchen falls on the 22nd day of the ninth month of the Tibetan lunar calendar, so its date on the Western calendar moves each year. The dates the source lists run from 31 October, in 2018, to 20 November, in 2016, and in 2021 it fell on 27 October.

The festival belongs to the Tibetan Buddhist world. Tibet, Bhutan and Sikkim are named as the places that observe it, and the article also lists Sri Lanka, Myanmar, Thailand and Laos, where it is kept on local lunar days under other names. Sankassa, in India, is the site where the Buddha is said to have come down.

What Lhabab Duchen means

Keeping the day is a way of gathering merit. In Tibetan Buddhist practice, good and bad actions are thought to weigh more heavily on this date, so people turn to prayer and virtue. The story behind it is about gratitude: the Buddha went to a gods' realm to repay his mother's kindness with teaching. The descent itself is remembered as one of the eight great events of his life, and his mother's attaining of arhatship is part of what the day honours.
