Your roles is to discipline your mind (Not allowing judgement, or unloving thoughts). I understand your question as i am a formal new age teacher. The clearing mind in their way is not of God. Not all their teaching is wrong for they us a great things and copies of the Catholic faith or Jesus teaching but your task with your mind, is to not give into thoughts that isn’t from love. If you worry, then offer your worry to God and ask him to give you faith. If you have resentment toward someone or a situation, pray God to help you to forgive through our lord.
Don’t worry about clearing your mind but instead, connect to God with your heart and allow yourself to feel this great gratitude to be with our lord through prayer. Pray for faith, trust and charity.
Blessing and love!
