If you want to be a Quantum theorist it requires a person to think about reality and the universe in a manner that is in contrast to something as tangible as classical Newtonian physics, and this requires the person to condition their body/mind and thought and so forth in order to practice the science. The Same is required for ALL Devotees of God, and each person must make the conscious changes in life to support the growth of Holiness or Holiness goes without notice. The Holiness a person Realizes in some kind of heaven is no Holier than right Now. The darkness that blinds the body/mind of God's Light is the ego self, and that is what is processed, purged, and ultimately Eternally destroyed via God's Grace, Fire and Power of Presence (the One Presence Over and Above All, the One that Is beyond death and birth, which is inherent in the Very existence of existence, thus IT IS Eternal). God Is Fully Capable of Living you without the ‘me’ being there to make sure everything is ok. Surrender into the Divine Holy Presence of God's Everlasting Heart~Fire~Joy-filled~Bliss.
In the beginning (to those just being Initiated by True Holiness), the Baptism of Holy~Fire through the Holy Spirit shakes (literally) a person to the core of Self Awareness, and this immediate and instant process takes a person’s consciousness beyond the inward sense of (ego) self. The actual experience of the Holy Spirit (for those just entering the beginning stage of Real Self understanding) will make a person shake, vibrate, swoon, and even pass-out. The reason for this experience is that the body/mind is not used to being Alive through God's Holy Presence; thus, the body/mind (still in its infancy of Realization) seeks to reject and not be Over-whelmed by God's Holiness – but that is exactly what happens, thus the body/mind tries to resist in all sorts of ways, and even shut the body/mind’s consciousness down (pass-out).
So, in the beginning a person’s response to the Over-Whelming Power of God's Holy Light is a play between the old habit of 'me' (self possession and self obsession - sin) fighting to keep its (egos) hold over the consciousness of the body, but because the person is learning how to surrender the 'me' for Truth (to consciously Transcend the ‘me’ contraction of consciousness), there will appear this kind of struggle of the 'me' verses God's Holy Spirit. This struggle will continue until the Holy Spirit of God has made plenty of Progress through the Transforming Power of what it Really means to Be~Holy. As time progresses and a person grows in living through God's perpetual and eternal Light (by greater and greater degrees of self surrender into God’s Eternal Expressed Image of Presence) the apparent struggle that manifested in the beginning will fade.
The Holy Spirit will eventually (by Grace and the Disciple's devotion to having the Fullness of God) gain a constant Hold Over the body/mind (with Its Always Tangible Heart~Fire Awareness/Feeling), and the Heart~Fire~Bliss of Holiness takes an Ongoing, Perpetual Seat in the chest region of the body/mind (in the three-heart region of the Spiritual Cross = spiritual body). The struggle disappears with the (progressive) purging of the ego self (sinner self), and the person's Living condition (moment to moment) becomes Radiant (with devotion and self surrender) with God's everlasting Heart~Fire (which is the Teacher - Teaching - and the Fire needed for the Process of God Revealing ItSelf to the individual). God Bless.
