The Thai name for Garuda is Paya Krut (sometimes seen as Krut Garuda).
Making offerings and chanting the mantra is believed to bring wordly success and wealth as well as spiritual protection. I’ve shown a typical amulet pendant – there are more in the Garuda Images category.
The mantra is:
Karubija Gidti Mandtang Ma
A U Om Payaa Krut Ruj Ruj Laew Ruay
Na Dai Ngern Na Dai Tong Na Dai Sap
Na Mettaa Na Jaroen
Na Man Kong Na Laang Aathan Atitaami
