6. Meditating on a concept.
Some meditative practices involve contemplation of an idea or scenario. An example is the “meditation on impermanence,” in which you focus on the impermanent nature of all things, starting with your thoughts and feelings as they come and go. In the Buddhist “meditation on the corpse,” you think about a body in the ground, as it slowly rots away and is fed on by worms. The technique is used to guide you to an understanding that your rationalizing mind might not bring you to.
