Some people view this world in dualities: Good and evil, true and false, above and below, inside and outside, young and old, past and future, and seemingly endless pairs of opposites. A knowledgeable person realizes that there are many perspectives in between; in fact, most of us usually live in those intermediate aspects. A truly wise person can see beyond the pairs to their potentials. There is a little good in every evil, some truths among the falsehoods, an upside to the downside, a within in the without, etc. and vice versa.
True mystics are aware of oneness in all. The many are transient manifestations of the One. Each is balanced by the other in the infinite here or offset by the other in the eternal now. What looks to be one thing there might be seen to be another elsewhere. What appeared correct yesterday may seem incorrect tomorrow. These mystics do not accept as Real any there or elsewhere, yesterday or tomorrow. They may appear real only in space and time.
Space and time are useful concepts* which we mere mortals - as temporary inhabitants of this whirling and relatively small mass called Earth - use to measure worldly life. We all actually exist here and now, although our minds often dwell on images which are spatially elsewhere or in alternate temporal spans. Our emotions and bodies, other aspects of our apparent triune being, mainly deal with here and now. Our inner self, or soul, is always here and now.
We seem apart from the world, although we always reside in this world. We are never separate from our soul, although we seldom do live in it. Mystics who live through their soul never feel detached from souls of different people, spirits of other living beings or sparks of inanimate objects which radiate from the endless divine essence. They do not experience any exclusion from physical surroundings: manifested from infinite divine matter. Also, their thoughts are not isolated from the minds of others: which are extensions of eternal divine consciousness. For them, perennial union is fact, certainty and unquestioned; diversity is simply passing appearances. They look beyond surface realities.
True mystics do not ignore separateness in temporary peril. In a fleeting existence as singular humans, they occupy an infinitesimal space called the body during a speck of time called this life. Most are compassionate and usually not concerned with the evils of others. Their higher regard is for the commonality, community and communion amongst all. Many of them do see this life as a partial disclosure, an incomplete manifestation or an unfinished revelation of the infinite divine.
Death seems to follow an eventual decay, a terminal illness or a fatal accident in separateness from eternal life. Divine union is unfulfilled within the concepts of space and time.
Too many of the rest of men and women ignore oneness in eternal jeopardy. This life seems to be their only reality; satisfying this self is their primary concern. They view the evils of others as threats to them, overlooking their causes. They usually exist in an emotional, mental and physical shell, interacting with most people in their own best interests. Every year and every day is filled with attention to their selfish, personal welfare. Thoughts of death are disregarded, postponed or feared. They shape God to their preferred image and rarely, if ever, consider eternal life. They alienate themselves from divine unity and, as a result, do not realize it (and do not care to).
