In their preaching, devotees often speak to the people about health
aspects of their vegetarian diet, and also about these and those
possible material benefits when people act like devotees are acting,
how devotees are living, etc.
One thing is sure, the forest is in the mode of goodness and as such
good for spiritual advancement. Even materialists can feel that they
are in lesser stress if they go to the nature or forest outside the city
or outside densely populated area.
But the problem arises when devotees try to impose to the people
different ideas that maby ordinary people would accept without
much thinking or research.
Still, there is this another type of people who are more informed
and do not easily accept things as they are presented to them.
One of such things that devotees often use in their preaching
is this point - "Vegetarians do not become ill with cancer." This
is simply not true. So many devotees and vegetarians became
ill and eventually died of cancer. This is also so with practically
all other diseases.
There are many points that are like this in the preaching of
devotees.
To conclude, my understanding is that devotees should look to
understand better spiritual subject matter so that their preaching
can become spiritualy surcharged and oriented, and that they
should avoid all such kind of material "promises" to the people.
