This short paper focuses on the sentences corresponding to the vajrayānamūlāpatti. The vajrayānamūlāpatti is well known as a certain fixed form. On closer inspection, however, there are cases to show an unique form either on its order or on its number of items (/contents) in some texts.
Fifteen sentences correspond to the vajrayānamūlāpatti in fourteen texts. As a result of examining each case, six show a small difference from the others. Among them, this paper takes up the forms in the Kṛṣṇayamāritantra and Kālacakratantra. The reason why there are variations in the vajrayānamūlāpatti is presumably that this rather important doctrine had been preached in a relatively free atmosphere by Buddhist monks at that period.
