Failure to experience silence, peace of mind, mental clarity, bliss, or other promoted benefit of meditation is not in itself a sign of incorrect practice or that one can't concentrate properly or concentrate enough to be good at meditation. Whether one experiences peace or bliss is not what is important. With regular practice one inevitably acquires an increased understanding of and proficiency with the particular meditation technique. Some people use the formal concentrative meditation as a preliminary step to practicing a mindfulness meditation during the day where one tries to maintain a calm but increased awareness of one's thoughts and actions during the day. For some people, meditation is primarily a spiritual practice, and in some cases the meditation practice may be closely tied to the practice of a religion such as, for example, Hinduism or Buddhism.
Relaxation is a common biproduct of meditation.
Relaxation itself can assume many forms, such as taking a hot bath or reclining in the Lazy-boy and watching tv, etc. Meditation is an active process where the meditator remains fully aware of what the awareness is doing. It also attempts to transcend the thought process whereas many forms of relaxation still engage the thought process. Meditation allows the body to relax and can offset the effects of stress both mentally and physically to a potentially much greater degree than passive relaxation. Constant thought-activity, especially of random nature, can tire the mind and even bring on headache.
