There is an area of value which the Geon from Villna was sensitive to--that is learning Torah and keeping mizvot in the most basic simple way possible. It seems to me that this is a hard area of value to hold on to. For one thing some people are on a different frequency anyway. \
It is like radio transmission. If you are tuned into the right frequency then you have got it but if you are even a fraction of a micron off all you get is static.
I was once tuned into this frequency. Loud and clear. .
I had a friend they went around with the Na Nach group of Breslov for a few years and he thinks that they in fact felt some kind of lift by saying Na Nach all the time. But that is not any different from what Hindu people feel when they say the mantra given to them by their Guru.
In conclusion I would like to suggest that there is no substitute for simple and basic learning Gemara, Rashi and Tosphot and keeping Torah in the most simple basic way possible. .
