Ānandavardhana categorizes a case of bitextuality (śleṣa) as involving reverberation, as both meanings do not occur to the reader simultaneously. Further he describes this as a case where the sentence (rather than individual words) suggests a second meaning, which comes like a “reverberation” or some time after the first. This supports the idea that reverberation is about processing time, rather than (or in addition to) a felt tension. Elsewhere, Ānandavardhana points out that for many kinds of suggestion, hearers do not have a “reverberation” or awareness of a gap between the primary meaning and what is suggested. Abhinavagupta gives an analogy to explain cases where there is no such reverberation. He says that when someone has taken to heart the relationship between smoke and fire, she will be able to reason inferentially to the existence of fire simply on the perceptual basis of smoke. There need not be any awareness of inferential processes on the part of the thinker.
