“Over a bowl of noodles [the younger Cantonese man] waxed eloquent on the subject of mantras. 'Ordinary people, Ah Jon, use mantras as spells to win good fortune or ward off disease and other evils. Perhaps they are right to do so, for the mantras are often successful, but I do not ask you to believe that. What I beg you to believe is that they are of the greatest help in altering states of consciousness. They do this by making your mind stay still instead of chasing after thoughts.'

He went on to explain that, being devoid of meaning, they do not promote conceptual thought as prayers, invocations and so forth are apt to do; and that, as each mantra has a mysterious correspondence (he could not explain what kind of correspondence) with the various potentialities embedded deeply in our consciousness […] it could cause one to snap into a state otherwise hard to reach. I do not remember his actual words, but I do remember that he was the first to voice an idea which was later to be abundantly confirmed by my own experience. […] he went on to say that to use meaningful words in any kind of religious practice is useless, since words encourage dualistic thought which hinders the mind from entering upon a truly spiritual state. His last words […] were: 'People who pray with words are just beginners. Don't do it!' Several passengers who understood English glanced at him as though they thought him a bit mad and I myself was quite taken aback by his un-Chinese vehemence, but I know now that he was eminently sane.”
