In order to find heaven on earth, our capacity to love must be purified. St. Elizabeth of the Trinity tells us that we cannot take great strides towards union with God as long as we desire things that are foreign to divine union. She uses the analogy of purifying gold, whereby through fire, the impurities are separated from the gold. It is in this way, that the soul is purified of worldly desires, which then allows the soul to love God more purely. She goes on to explain how this refinery is located within us. As we learn to spend time with the indwelling Trinity, we are drawn to love, and through the power of the Holy Spirit, we learn to let go of worldly things.
Learning to take these desires to the refinery located within is very hard. The process reminds me of the story of the transfiguration. God reveals wonderful things to the select disciples, and in response, Peter longs to get busy; to build tents. Mt 17:1-8. In this way, so, too, do we become restless when confronted with the awesomeness of the indwelling Trinity. There is a part of us that longs to stay rooted in worldly things, and there is likewise a part of us that longs to do the job ourselves. However, God calls us to be like children, and to let him do the heavy lifting. A part of us rebels and wants to claim that this is not the only way. Unfortunately, other than St. Paul, who had his own type of burning experience, I have yet to read of a saint who has attained a significant level of holiness without seeking it in the eternal flames that come to rest within us at baptism.
Having said that this is the way, there are many approaches to this process. It usually starts with some form of meditation. In pondering the words of Jesus, as Mary, his mother, taught us, we are led to silence. In fact, at some point in meditation, one should start to notice a desire for silence over meditation. When this happens, one should seek to follow the Holy Spirit in this direction. There are also forms of prayer that can be used to jumpstart silence. In the end, the Holy Spirit directs us all on a unique, but substantially similar path towards the interior life. All we need to do is to seek him and to ask the Holy Spirit to guide us on the path.
God wants to have a deep and personal interior relationship with each one of us. He wants to love away our hurts, pains, and misunderstandings. He wants to teach us how a deep love of him provides the fulfillment for which we all seek. He wants us to know how we can live life to the fullest with him.
Spend some time with the Holy Spirit. Share with him your reservations and your heartfelt desires. Ask him how to take these things to the refinery within. Ask him to burn away all that is unholy, all that keeps you from living in true freedom. Ask him to help you see when you are resisting. Ask him for the grace to be like a child so that you might better submit to this process. Ask him to help you persevere, even when the fires of purification burn hot. When you find yourself resisting, ask for his forgiveness, and for a stronger desire to submit to the process.
