What is the purpose of the Osho talks?
The basic purpose of the Osho talks is to provide an opportunity for the listener to experience meditation. And listening is very different from just 'hearing.'
In this way, these talks are unique. They are basically an experiment, and the listeners are the experimenters.
Just as the Active Meditations are a bridge to help restless modern people enjoy a taste of meditation, so too, talking is used as a way of solving the oldest dilemma in the history of meditation – how to experience silence with no effort.
