Amazing instance of a 2nd text being written in interlinear fashion, but upside down in relation to the 1st text. The 2nd text, which starts out right-side up, has the opening of a Sutra text, with the Bhagavan dwelling in Mnyan yod. The 1st text is a very tantric one. I noticed use of sbom ba and ming chen for two organs. (Dan Martin's Hurried Notes)
