Upholding the Great Secret Mantra
The tantra known as Upholding the Great Secret Mantra (Skt. Mahāmantrānudhāraṇi, Tib. གསང་སྔགས་ཆེན་པོ་རྗེས་སུ་འཛིན་པ།, Wyl. gsang sngags chen po rjes su 'dzin pa) is found in the Kriyātantra section of the Tibetan Kangyur (Toh. 563).
This tantra is one of five texts that together constitute the Pañcarakṣā scriptural collection, popular for centuries as an important facet of Mahāyāna-Vajrayāna Buddhism’s traditional approach to personal and communal misfortunes of all kinds. It addresses a range of human ailments, as well as misfortunes such as robbery, natural disaster, and criminal punishment, thought to be brought on especially through the animosity of non-human spirit entities.
