OP: Aren’t you looking more at the practitioners and less at the practices? If so, that is a mistake! If you see arrogance and ego, you are looking at others but seeing yourself. That is true with each of us. It is our lifelong battle.
Silence is greatly needed on a daily basis for genuine growth in the spiritual life. Silence that is so difficult to find in this culture. The faith has the perfect tools for this, if we have the discipline to apply them. God is present in all of the noise, but disguised or obscured by it. He revealed Himself to Elijah in the still, small voice.
There is a spirit which is driving all sorts of corruption into the faith - mostly eastern practices which mimic the faith, but which place us in spiritual jeopardy. From the misapplication of labyrinths to yoga to eastern “centering” prayer and meditative forms there are assaults from every side. Remember that our battles are not against flesh and blood - but in the spiritual realm!
For this reason, the Church offers spiritual direction and guidance. Authoritative direction, not pop-culture fluff.
Not everything you mention is bad. Contemplative prayers and meditative prayer are simply excellent. Still, one must know the definitions so as to discern which is which and which is the best fit. Current attempts to mold Catholicism to eastern spirituality (or vice versa) are inherently dangerous. I will be hammered for this, but Thomas Merton was seduced by Buddhism, which in particular, teaches the emptying of self. How does that square with the Christian faith?
We are Tabernacles of the Holy Spirit! He fills us - He does not empty us. We do not divorce ourselves from this world, losing all hope, expectation and anticipation. Rather, we are filled with faith, hope and love. We are called to activity when we are not in silence - listening to the voice of God speak to us.
Whichever spirituality we choose is intended not only for personal growth, but to equip us to grow the Church. It must sqare with the teaching of the faith - which is not a fence to keep us in, but a barrier to keep evil out! It is there for our temporal and eternal protection. We cross over it at great risk.
If our confessors are not comfortable providing spiritual direction, they certainly know of many others within the faith who are.
Ask and you shall receive.
