Wan Kongchak Phra In

Ritual purpose

Primary: คงกระพันชาตรี when carried or eaten. Secondary: invulnerability, metta, authority, enemy suppression; also non-occult medicinal uses for eye disease and abdominal wind.

Botanical

Curcuma sp. (Zingiberaceae); the rhizome and side branches can resemble a discus/chakra. BanVanThai warns the tuber strongly resembles ว่านมหาเมฆ and must be examined carefully.

Origin / legend

No narrative legend; the "Indra's discus" name appears morphological/symbolic.

Consecration method (ปลุกเสก)

Carry or eat; before eating recite the stated katha according to weekday count ("ตามกำลังวัน"). An alternative tradition: empower fresh tuber with the Five-Buddha katha or a short formula 3 times, then eat.

Katha (คาถา)

• อุทธัง อัทโธ นะโม พุทธายะ จะพะกะสะ พุทธะสังมิ

  utthang attho na mo phut tha ya cha pha ka sa phuttha sang mi

  Opaque Pali-like protective formula including homage to the Buddha; recited before eating per weekday count.

• กันหะเนหะ

  kan ha ne ha

  Alternative short formula, recited 3 times; opaque.

Application

Carry on the body; eat fresh tuber after katha; non-ritual medicinal prep as eye drops or for wind-related abdominal conditions.

Taboos / restrictions (ข้อห้าม)

• Do not confuse with ว่านมหาเมฆ.
