Meditation and the sole use of meditation to enlighten and align yourself with your true self is one way to achieve wholeness and sole fo fillment in your physical life. It is a major thread that runs through time and many cultures that aspire to achieve a higher level of consciousness. It is my belief that this is a major aspect of development but no the sole aspect currently. We have become so used to this physical life / body that we need some sort of kickstart or proof that we are energy beings renting this physical body on a journey to experience more and more for the development of our souls/ energy. I personal use meditations daily and would highly recommend them but I also recommend to start very basic.
