How to stop thinking about metaphysical questions? I have been practicing seriously for a month now. I'm mindful a lot of the time but not 100% yet and whenever I'm not I start thinking about metaphysical questions or what could be after death or if it is nothing etc. How can I stop this? Or how to stop thinking about something in general when you don't want to? For some reason I can't be equanimous with metaphysical questions. They run through my head like there's no tomorrow and nothing more important than that. It's quite annoying. Would noting help?
Practice Vipassana meditation using breath or walking. This will help you to contemplate on wholesome thought. If you want to stop Vitakka and Vicara you have to practice Samatha meditation. Vitakka and Vicara stop at second Jhana which is I have not experienced myself. Being aware that your mind is unrest alone is meditation. If you can increase this awareness, you will improve your meditation eventually.
