No, there is no need for one to become Spiritual because you are already Spiritual. Unfortunately this word and its meaning got mangled long back which brewed an uncomfortable feeling among people due ignorance. Modern science has confirmed that every particle in our huge cosmos is a result of a flow of spiritual energy (spirit of God) emanated out of a single point but scientific analysis could not reach that point this far. Spirituality is that part of science which deals with the characteristics of this precious Energy. Unlike conventional science, the approach to gain wisdom on this subject is different, but extremely purposeful; much needed today for an effective Transformation. Human Spiritual-science presents an option to understand our true nature and help ourselves or; otherwise remain locked-up within our misery.
