 What irks Sapaṇ the most, it would seem, is what he sees as an attempt to excuse carelessness by appealing to the fact that rituals are only conventional constructions. He concludes the point by saying that all rites belong to conventional reality: Disciples, Great Vehicle, and Mantra rites. If you accept any of the systems, you must accept them in their entirety; you must do all, or none. There is no option to make a distinction between essential and non-essential doctrines based on the distinction between conventional and ultimate. The ultimate simply does not enter into the consideration of whether a rite or ritual—or, for that matter, any karma, any act—is  appropriate.[18]  The separate systems have each been handed down through valid lineages with their own integrity, valued and delimited always by their conventional utility. The fact that they are not ultimate is not an excuse to experiment or play fast and loose with the rituals and their interpretation. Everything that we can do, everything that we can say, is only conventional; but that fact does not license the blurring of the lines between the effective, well delineated paths taught by the Buddha that can lead us to liberation if we follow them with care.
