The father, who identifies himself as the author of both, has written praises for both brothers. Furthermore, the following two arguments inspire us to consider the sutrakara and bhashyakara as one:
1. In the initial articles and in several places in the commentary, the terms "kahiśu" in the sense of "vafa" and "vichara" indicate the first person, and according to the commitment made in that indication, it has been reiterated in the sutra; therefore, there is no doubt about considering both the sutra and commentary as a singular creation.
2. When reviewing the commentary up to that point, one thing brings a smile to the mind, which is that at no place has there been any struggle in interpreting the sutra; there has been no ambiguity in interpreting the sutra if there were options; moreover, no alternative interpretation of the sutra has been presented, and at no point has the sutra been subjected to any textual variation.
This situation validates the longstanding belief that the sutra and commentary are unified. Where the author of the original and the commentary states: "तत्त्वार्थाधिगमाख्यं बह्वर्थे संग्रह लघुग्रन्थम्। वक्ष्यामि शिष्यहितमिममहद्वचनैकदेशस्य। २२ ॥" (I will explain this concise text on the subject matter for the benefit of the disciple), it corresponds to a passage in the treatment of the path to liberation.
