Guided meditation can be very helpful for beginners because someone else leads you in your effort to relax and enter a meditative state. These are usually narrated through instruction, stories, imagery or music and can be accessed via a sound file (mp3, CD/DVD, etc.) on your computer, phone, tablet or by video. Guided meditation uses the senses. You utilize smells, sights, sounds and textures to visualize various methods of relaxation. Often, you follow along as a guide offers directions on how to breathe, relax muscle groups and create a sensation of inner peace. There are many audio apps, CD/DVD and other forms of meditation available now that use binaural beats to facilitate deep meditation very quickly. These beats synchronize brain waves so that the frequencies are altered to help the mind reach various states of consciousness. Concentrative meditation has you focusing your attention on an image, object, sound or positive mantra. You can think of a peaceful beach, a bright apple or a calming word or phrase. The idea is that what you choose to focus on helps block out distracting thoughts.  For your mantra, repeat a word or phrase that calms you. You can choose something like “I feel at peace” or “I love myself” but really anything that makes you feel better will work. You can say it out loud or silently, whichever you prefer.  It can be helpful to place a hand on your stomach so you can feel your breathing while you practice controlled breaths, visualizing or mantra repetition. Consider Japa meditation. It utilizes the repetition of a Sanskrit term or word along with a beaded rosary to meditate. You may also want to try passage meditation, which uses spiritual or inspirational passages to focus and achieve meditation. Meditating this way focuses your attention on the present moment. You bring awareness to what is happening right now and your experience during meditation, such as your breathing. You recognize what you feel, think and what is happening around you without actively trying to change it. ...
