Holistic, or "wholistic", healing is all about healing the person and his/her issues on a total mind -body -spirit connection. The person, on all levels, has issues that need to be focused and worked on.
For mind issues, these can be anything ranging from mental status, positive mindsets, affirmations, thought patterns, and even things such as brainwave concerns. You may head to https://newlifeexpo.com/ny-expo/new-york-exhibitors/, if you need to know more about holistic healing and its techniques.
Body issues are dealing with your physical body and the concerns you are facing with ailments or "dis-ease." Working on body issues from a holistic aspect are working on things concerning energy balancing, healing, chakra and aura work, grounding and centering aspects, tapping into your own personal power, and learning multiple ways of establishing your connection with your own physical body. Once you understand this connection, you can learn how to tap into ways of balancing out concerns that arise within a physical format.
Spirit issues can come in a variety of ways; such as meditation, connecting with your spirit guides, working with your higher-self, tapping into other realms and planes of existence, and working on developing your own strong connections from within.
For a holistic approach to any area of your life, you can apply these concepts for a mind-body-spirit method. For example, if you are concerned about money in your life, look at it from all areas. From a mind concept, how are your thought patterns influencing your money relationships in your life? From a body concept, are you giving everything you can towards the goal you want to reach?
