"the deepest need of our darkness is to comprehend the light which shines in the midst of it...the monastic life is a rejection of that which obstructs the spiritual rays of this mysterious light"
asceticism disposes the soul for union with god, it's the recovery of our true selves created for union with God, it's a purification and a liberation. however asceticism when misused to serve ourselves instead of God, can often harden our hearts and blind us from his grace and light. as St Benard said "woe to those who carry the cross of Christ and do not follow Christ; to those who share in his sufferings, and yet refuse to follow him in his humility". pursuing self-discipline to simply appear in a certain way to others or ourselves, just isn't the way. we pursue such things to better open ourselves up to HIM and for HIM only, others need not know what we do, neither should we ourselves be dwelling on and thinking ourselves the better for it all. sp, any asceticism we take part in, any sort of discipline, should always be rooted in humility and obedience to Christ, and just Christ in general lest it lead us astray from Him and towards pride, airs of superiority, etc
"man, created in the image of God loses his likeness to God by becoming centered on himself" -- through deepening our faith and our relationship with Him, by allowing ourselves to lose all and any selfish motivations in life, we become more like Him and thus more like our true selves, puritas cordis is a heart that is empty of self, and it is a puritas cordis we need to seek in order for Him to fill us with his spirit and love instead
