Greetings 61435,
One must realise that there are at least two sides to every story, thus what you have read may well have been contrived by another who only wishes to cause upheaval. Whether or not what is written is true one cannot be certain, so I find it unwise to jump on the bandwagon with so little information and no evidence whatsoever. I must state, however, that having studied "Jasmuheen" somewhat I do not believe she lives the lifestyle she dictates -- one only needs to read one of her countless books to realise that her "teachings" revolve around ME-ME-ME ideology more than they pertain to actual Breatharianism!
You said it best yourself when you said: "Jasmuheen's followers, who believe..." Unfortunately, much of humanity requires to be led, hence their will to follow; furthermore, when one has found his or her niche and is content to follow his or her chosen teacher, then the will to believe is subsequently magnified ten-fold (at least). Reason, logic and temperance are veiled, for the "master teacher" can do or speak no wrong...! The false messiah-deluded student mentality is rife in all places...even here.
Having said all that, I do firmly believe that we are all capable of studying text of all natures and discerning for ourselves what is truth or lies, right or wrong, regardless of the integrity of the writer. After all, figures such as Jasmuheen and Wiley Brooks may be noticeably imperfect whilst dictating perfectionism, but this does not stop "us" from gleaning goodness from their false sentiments, achieving purity through coherence so as to heighten our own consciousness.
I am not recommending you read Jasmuheen's work, nor would I ever recommend her writings to another, but I do feel that we should all concentrate more on ascendance (physically of course, but especially mentally, and even more so, spiritually) rather than berating another whom we shall never encounter in the flesh...
