Meditative thought is a concept often associated with ZEN, a school of Mahayana Buddhism that emphasizes the value of meditation and insight. ZEN is a three-letter word that can be used to describe meditative thought, which is a practice of focusing one's mind on a particular object or thought in order to achieve a state of mental clarity and inner peace. Meditative thought can also involve contemplation of spiritual or philosophical topics, such as the nature of existence or the interconnectedness of all things.
