Meditation works with all belief systems, unless of course you believe it to be a demonic or harmful activity. In which case you don’t understand meditation. It is ultimately unavoidable for any human to go their whole life without it. Many of us mediate daily and aren’t even aware we are doing it just because the label of the activity is changed. Every time you consciously choose to do something to relax or to cultivate joy you are in one way or another partaking in an act of meditation. Although this may not be the “Empty your mind” technique everyone classifies as the true definition of “Meditating” it is still nonetheless an extension of the experience. In my current understanding, none of the popular religions or belief systems have banned meditation or considered it a forbidden act. In fact, many of them are fully supportive of it (Although they may not know it). Prayer for example is a type of meditation in which you communicate with a higher force. It calms the mind and helps you cultivate feelings of joy, hope, power, peace, and so forth. It does not matter what religion you follow, what Gods or Goddesses you believe in (Or disbelieve in i.e. atheism), or what facts you have determined to be true in your life experience. Meditation is here to benefit all and does not rely on any of that for it to be an advantage to you. It is about journeying to the deepest realms of your being and exploring the endless depths of your spirit. It is about getting to know who you truly are behind all the layers, ideas, and concepts. It is about freeing the imagination and uncovering hidden truths that dwell beneath the normal realms of consciousness. Meditation will not interfere with your beliefs in a negative manner but might influence the dissolution of that which does not benefit your soul. Meaning, if you believe in something that is harmful to you or keeps you from experiencing harmony, meditation will help you change it. However, it is important to know that you are always fully in control. You are not strapped in for the ride. If you want to stop all you have to do is open your eyes and do something else. Meditation is not here to force you to do or become anything that you do not want to become. It is here to help you cultivate energy, align with truth, and explore deeper realms of your being in accordance with your will.
The benefit of meditation is truly endless and is a suitable practice for anyone and everyone regardless of what you choose to or choose not to believe in.
