​The Saṃvarodayatantra (also known as Saṃvarodaya or Samvarodaya Tantra) is a significant Buddhist tantric text associated with the Cakrasaṃvara cycle, a central tradition within Vajrayāna Buddhism. Comprising 33 chapters, it delves into advanced yogic practices, ritual frameworks, and esoteric teachings. Seems to be written by two different scribes given the difference in handwriting from fol 27a onward. Annotations and corrections made on the mss. in black ink.
