Overthinking, anxiety and depression these all comes from your thoughts. The more you try to control them the more you drown in them. I don't believe in meditation, breathing techniques...... These all are bull$*it. Let me tell you something practical. First let's be clear, we cannot stop our thoughts, it's impossible to stop your thoughts. If I tell you to stop thinking about a Pink Crocodile you will definitely think about it. All we can do is observe your thoughts. Yeah, observe them like you observe a still photograph, never convert them into a video means, thinking about past and future of the thought that has appeared. If you do so, it is like pouring fuel into your thought fire. Keep separating yourself from your thoughts. Just observe them as you observe the parade of military planes flying one after the other. For the first time, you are observing the thought producing machine. All the best. Please remember no religion, no meditation, no ritual and nothing is required to master yourself but this simple observation. Thank you.
