It is quite possible to have a preference for silence rather than being chanted at in Hindi (a language I have absolutely no knowledge of) or Pali (without translation)...
The long chant is only in the morning not all day. If anyone has a “preference for silence” he/she can meditate in the pagoda cells or in his/her room during the day.
...without being accused of aversion or a lack of understanding
Continuing reacting with aversion towards chanting or anything else instead of try to maintain equanimity shows a lack of understanding of the technique and the instructions given in the discourses.
I am afraid to say that the idea of 'magical words' or should I say 'creating good vibrations' does not really sit well with me
Goenkaji never said that his words are "magical".
The phrase 'creating good vibrations' is used often by Mr Goenka in the discourses.
Really? The phrase 'creating good vibrations' is used "often" in the discourses? I don't remember, maybe I missed that part.
The Buddha never made such claims, the Buddha seemed to generate goodness through his teachings which were understood by others and not through special chanting or languages that were unintelligible to his audience
The discourses with the Dhamma teachings and the meditation instructions are given in a language intelligible to the audience not in pali or hindi. And by the way you hardly are an authority in what the Buddha taught or not.
Being heavily involved with Tibetan Buddhism in my early years, I have seen the utter ludicrousness of large groups of westerners chanting & being chanted at, in a language totally alien to them and totally believing that this is a mystical language bringing its blessings.
There is nothing mystical in Goenkaji chants and certainly he never said that the chanting will help you to become liberated. Liberation comes only with your personal effort, as he says:“Dhamma is Dhamma only if it makes us self-reliant. So it is the duty of every Vipassana teacher to teach people to become self-reliant. "Attā hi attano nātho" You are your own master and no one else. "Attā hi attano gati" You make your own future, both wholesome and unwholesome and also the state of full liberation beyond all conditioned states. If you understand this properly, no teacher will be able to harm you in any way. Then if any teacher says, "Sit in front of me for one hour, I will give mettā and suck out all your sins," you will get up and walk away because you don't want this kind of mettā.”
