Master Yinguang once said this (see "Master Yinguang's Notes, Part Three", Volume 1, Volume 1, Chapter 59 Page): White Clothes Curse, no source found. However, those who think sincerely will get everything they ask for, and will obey whatever they wish. Note: The ‘White-robed Master’s Divine Curse’ is the ‘White-robed Curse’.

This mantra can be found in the 60th "Curse Chapter" of the "Fa Yuan Zhu Lin" in the "Tibet" and the 68th "Curse Department". The name is ‘Suiwan Dharani’. This mantra was first seen in the 60th Mantra Chapter 68 Miscellaneous Mantra Part 7 of the Zhulin Volume of Fayuan.

The Sanskrit pronunciation of the mantra is roughly the same as the mantra of the Great Master in White. 'Twelve thousand times', you will get everything you wish for, so the mantra of the great man in white must have come from this. Fa Yuan Zhu Lin was written in the Tang Dynasty, so we know that this mantra was already popular before the Tang Dynasty.
