"those of good want us to choose to do good, out of pure love","When you can truly see and understand this, becoming as they are becomes simple","you become more capable of enduring it, because its the right way to be." (picked a few pieces out but addressing it's entirety)

I LIKE THAT, a bountiful spring of Pure love that flows thru you, enabling you capable of enduring all. If I'm understanding you correctly, the love of God's grace isn't a love that emanates from within, its a divine love that flows thru you. A distinction with major implications. It's an unadulterated love untainted by human frailties and or confliction, the only source of Pure Love is Divine Love and Divine Love can only flow thru you. Becoming the vector is the spiritual journey of, choice by choice. Being the vessel is the only path to experiencing divine love. I LIKE THAT (maybe there is a place for Selfless love in this world)

'wanting to protect them is itself a need and a desire that is based upon our own personal understanding and judgment, it is both selfless yet selfish and the latter is what is difficult to reconcile at first glance'

I understand the sticky side of selfish love, how true, reconciliation is difficult in quantifying and qualifying both. Honest evaluations of motivation can lead to uncomfortable self discoveries, constant vigilance is required to ensure integrity of intentions and action and or non action. A life beyond scripts and games is a life of deliberate action, not a cycle of per-programmed responses running on automation. It's demanding, but richly rewarding as it pays dividends of self awareness and critical evaluations both internal and external.

Selfless Love, an aspiration worth striving for (as mention above). In the physical realm I'm not sure it's completely possible, I think as closes as we mere mortal can experience Selfless love, is the bond of mother and child, as it's origins begins in the singularity of both, blurring the lines of individuality giving justification of self selflessness.(but even then the mother has a vested interest in the propagation of her DNA) The child however strives to claim the right of self the moment the umbilical chord is cut, and pursues an all out rebellion of independence by the time it's two. It's the second separation that brings the most pain to the mother, I think. I'm assuming you're female, maybe a mother as well, and probably understand this much more intimately than I ever could.

"I truly believe the great difficulty of it marks it as one of the cornerstones of true growth, this must be the path to becoming more than we've been our entire lives. In this way, I think I can see God's intention of it all."

Beyond insightful, spirituality enlightening, understanding this as it applies to my struggle of accepting the choices those near and dear to my heart have made, it surrenders their destiny onto Gods hands, as he is infinity more capable of leading them, than, I am, ever was, or ever will be. I can parse the difference between "duty to defend" and "obligation to release" them unto God to lead them as he will. And as you so eloquently stated the consequence of their choices whither bliss or blithe befalls them becomes bearable in my heart for I know "yet detachment for the child before them struggles to grow", And Gods Love is infinitely more supreme than mine.

"accepting that there is no way out (for the ego), is the only way out (beyond the ego)"

I hear you and know truth is there, the vessel void of ego is capable of receiving more of lifes gifts as the ego displaces and distorts the true nature of things. The Dio teaches us, the value of the vessel is the empty space it creates, not the fancy fanfare etched on its side. Easier said than done, where I go therefor my ego goes, and that brand is deep, all the way to the bone.

Thank you for taking the time to share your thoughts, I find them most enlighten. :-)
