Just let him be ...

When all possible choices within the dream of separation have been made, have been tasted, have been felt and have been known, finally there emerges the still, quiet voice of Spirit that speaks through the soul, whispering of the one Truth, the one Reality, the one Love, the one peace and the one bliss that is continual.
(The Way of Mastery)

How can you consider yourself spiritual superior to anyone? Do you really know what your brother already lived through? Maybe it is just that little taste for greed, or that blinding drive of lust, or the depth of depression and despair that brings his ultimate break-through. I have stopped losing sleep over anyone and instead zoom into the moment, the sister’s smile and the beauty of the situation. Just leave your brother in peace; one day Spirit might speak through him, possibly even today when you meet him.
