Meditation is a Buddhist term, which can have two meanings, one refers to the skill of meditation, and the other refers to the state of meditation. When it comes to meditation techniques, the narrow sense of meditation is only used to refer to the meditation techniques of Zen Buddhism in Han Dynasty, mainly focusing on stopping (the technique of stopping thinking and observing images) and observing (the technique of realizing thinking and observing images); Broadly speaking, you can also refer to the meditation techniques of other Buddhist sects and even Hinduism (because Hinduism and Buddhism have deep roots and have similarities in practice, but in fact, Hindu practice is more complicated). As for the meditation state, it is not easy to describe it in language, which is the common feature of mysticism experience, that is, beyond language description. If we must say it, it can be temporarily understood as: the past does not chase, the future does not rise, and now it is settled, and there is a clear and clear state. Meditation is also hierarchical, and the feelings of each level may be different.
