Why do we practice meditation? To be free of suffering… We can all describe suffering in our own particular way, however we all have it. The question is what do we do about it, going after other things or running away will not solve things, the solution is in your mind.
What is right effort when you meditate according to the Buddhist Sutras? There is at the end a very interesting Q&A that covers how to breathe. This talk was the basis of the next ones, where different aspects of the Q&A were developed.
The Buddha explains that to be free from suffering the only thing you need to practice is mindfulness of the breath.
