Buddhist approaches vary depending on school of thought, but one of the most commonly used methods is mantra. I met monks and nuns from South Korea, India, Burma, Tibet, and Japan who use this type of meditation. Essentially, the method of mantra allows you to create an independent from your attachments (which are all those experiences that trigger an emotional or mental reaction from you) point and to solidify it by training to concentrate on that mantra 24/7. The details on how to use mantra can easily get overwhelming, but basically it allows you to observe all and any experiences coming and going through your mind without discrimination, that is, it helps you to train yourself not to pay more attention to your emotions than to the little dot on the floor that you’re staring at when you meditate.
