I read one interview with Steve und Rosemary Weissman (vipassana teaching married couple), which shows the curiosity and its effects very well (free translated):
Question: You empathic the practice in daily life and the development of ethical conduct. Is that also a way of so called engaged Buddhism? Glassman Roshi says that enlightenment is seen in the deeds for others. How do you see that?
Steve: The Title of our last lecture in our 20-day-retreat was called "Make more". We good-by them in saying: "Make more!" We do not know what they will do in our society. But we encourage them to go on in making more in all possible sections. Once we had an manager in our course and he war really down but the retreat had changed him a lot. After three years we met him again and asked him what he is about. He said: "I am grown to a smuggler." We where shocked, but he laughed: "I smuggle food and useful things to Burma." Wonderful. That was somebody who had done more, inspired by us.
Even the most people would think, that is the way it should be, I was not about thinking "wonderful" when read this as both of them but so much effort into teaching people virtue as a very important necessary for effective ways of compassion and real success for the welfare of others. But at the point as they need to face the worldly pressure of that so called "engaged" Buddhism, they need to make a trade-off, of of their deep faith that virtue is the biggest help.
And that is what happens. Rather than people would adopt this ways of live, and focus on virtue they try to keep their ways alive and seek for possibilities to balance taking and giving for some better mental degrees and in this way they turn the way of destruction and new addiction on.
There are the lessons of gratitude
and but we easily oversee the way leading out of them but even increase attachments as we do not like to have any dept.
So spiritual tourism is a way that will easily lead to close the doors as the intentions are often not like the way of life was there since a long time.
"Long have you thus experienced stress, experienced pain, experienced loss, swelling the cemeteries — enough to become disenchanted with all fabricated things, enough to become dispassionate, enough to be released."
— SN 15.14-19
Not to forget, that the invitation to spiritual tourism has its simply worldly causes and are just binding deals. Better than to show gratitude to a country, a nation or what every we might feel as secure as our subject to pay back is to develop virtue, concentration and discernment and show gratitude to our teachers till we are free of every dept.
Please do not regard this as a generalization but this things will go along the natural mainstream of humans. People just take and they take what they think that it will make them more happy, they do not easily take the medicine in the right way.
