In [passages] like "One desiring heaven should perform the Agniṣṭoma sacrifice," if the inability of all humans to create such a sequence of letters were certain, then there would be certainty of pervasion; however, that very [certainty] cannot be determined by one who is not omniscient - this is what [the verse] beginning with "samastanaradharmāṇām" shows.
