Wan Kwak Mae Thong Bai

Ritual purpose

Strong commerce luck: calling customers, calling wealth, regular luck, metta/being liked.

Botanical

Hymenocallis spp. (Amaryllidaceae). SaimHerbal warns of significant naming confusion with similar "สิบแสน"-like forms.

Origin / legend

No narrative legend; the social/folk frame is that older merchants prized it as a shop-front plant, and correct identification often requires asking older growers.

Consecration method (ปลุกเสก)

When it flowers, tie/offer multicolored silk cloth (ผ้าแพรหลากสี), recite the receiving-blessing katha 3 times, then make the request. Plant in the sixth lunar month on a waxing-moon holy day or Thursday, in sandy loam mixed with rain-tree leaves, without fully burying the bulb. Consecrate the water with "นะโมพุทธายะ" 3 times before every watering.

Katha (คาถา)

• มหาลาโภโหตุภะวันตุเม

  maha labho hotu bhavantu me

  "May great gain/fortune come to me" — recited at flowering with the silk offering.

• นะโมพุทธายะ

  namo buddhaya

  Homage to the Buddha — used to consecrate the watering water.

Application

Plant in front of a house or shop; worship/care for it regularly; offer silk and recite katha at flowering.

Taboos / restrictions (ข้อห้าม)

• Do not cover the bulb fully when planting; avoid rot through excessive burial/water.
