Sigh you either didn't read my explanation or ignored it. "Better" is an equivocal term. Thus we have to apply a hermeneutic to bring Christ's words to meaning. Better in this case does not mean that the contemplative is a superior vocation. Vocation to the one discerning is not an "object" they need to find, but a possibility among many that we cultivate in and through our relationship with God. It is not like buried treasure, but rather a project that one cooperatively builds with God. To say one vocation is better form a theoretical mode (like when Aquinas say religious life is best in the Summa) has zero existential import on the discernment of the one discerning. Precisely because they are not searching for a theoretical object, but rather building a project; a way of being in the world serving God. Thus, one's vocation, if authentically discerned, is what is best for them! This is what Christ meant. Mary's vocation is what is best for her and that will not be taken away
