As far as the subject of parittas is concerned, the Milindapañha and commentaries are our only source of information. As the Buddha rejected haphazardism (ahetukavāda) there must be some kind of causal factors that make parittas work. Those stated in the commentaries seem very plausible to me.
(a) Four accomplishments of a reciter
(1) The reciter must be capable of reciting passages, phrases, syllables of the Pali text
with correct mode of articulation, enunciation, and accent.
(2) He must have full and exact understanding of the PÈli text he is reciting.
(3) The reciter should chant paritta without expectation of gifts or presents.
(4) Paritta should be recited with a pure heart full of loving-kindness and compassion.
And (b) of listener
where one need to be very attentive .
I think to fulfill the criteria or factor of
(a) 1 is not possible for many many buddhist . Pali words seems so distant for many people .
(b) the person need to focus their mind on the paritta chanting in order to be effective , but ,
when a person is dying or an animal near death ,
How is it possible to achieve such task ?
I suppose the benefits of chanting paritta is there but obviously Not Necessarily need to fulfill completely in accordance to such terms and conditions to be effective .
