The Blessed Virgin Mary is the burning bush because she burns brightly and fully, but is never consumed. The Lord Jesus is contained within her as the New Ark, along with a perpetual flow of Trinitarian Love. Amidst this fire, she is also perpetually the fountain of grace rooted in living waters as one 'who meditates upon the law day and night without ceasing. She is like a tree planted near streams of water, that yields its fruit in due season; Its leaves never wither; whatever he does prospers' [Ps 1:2-3], so she is in perfect balance and equalibrium. In other words, she does not ever become emotionally overheated! Her feelings do not consume her in a way that she becomes a flamethrower or a dangerous conflagration that spills out in a haphazard or chaotic way. Instead, she ponders all things in Her Immaculate Heart, and is thereby able to respond to any situation, event or circumstance, whether seemingly positive of negative, good or evil, with complete calm. She is 'full of grace' and contains such purity as the New Eve that she receives the flow of Trinitarian Love within which burns as a perpetual lantern of light and love for her spiritual children. By maintaining this equanimity and being perpetually focused on the Divine Will and giving her fiat in each present moment, she contains all within this perfect burning flame of the Holy Spirit.
She is also grounded [no pun intended] in the rich soil of humility. She knows that Her Son is the vine and she is the branches and without Him, she can do nothing. The elements within her very being as contained in the image of the burning bush are completely in balance, with no excess or deficit of any emotion. This allows her to respond in the fullness of grace and calm, in the midst of experiencing feelings and emotions at the deepest levels due to her open Immaculate Heart, her perfect sensitivities to the Divine Will and to the sufferings of both her Son, Jesus, as well as to all of humanity. Yet, she stands at the foot of the Cross in total equanimity. She gathers with the Apostles in the Upper Room in a calm way that unites everyone together in holy expectation, prayerfulness, silence, and harmony. This fire of love burning within her reflects and glorifies the Holy Three.
As the Burning Bush, she invites us to stay in her Immaculate Heart and Womb perpetually as each contains the proper boundaries to live in such harmony. As one seeking to surrender more to dwelling within the beauty and grace of Her Womb, Our Lady gently molds and shapes us in her tender maternal love, and assists us in avoiding impulsivity or unbalanced reactivity to unforeseen situations. She helps to ensure that one's passions and zeal do not become an unwieldy firestorm that leads to confusion, heightened anxiety, division or tensions. She teaches us how to hold 'this little light of mine' in an orderly way that does not hurt one's relationship with God, with others, or with oneself.
She also brings us to her Divine Spouse, the Holy Spirit or 'Ruah' breath of life, who leads and guides us in strengthening and developing stronger virtues in a spirit of emotional calm. This literally assists us in breathing calmly to receive grace and release emotional overloads that stir dangerous firestorms interiorly and to instead gain composure and embrace the present moment with a docile spirit.
The journey is arduous and I have a very long way to go, but this beautiful symbol and title of Our Lady has definitely assisted me in making wee baby steps towards increased self-awareness regarding emotional eqanimity and freedom that is expressed in healthy and loving ways. It has helped to ground me in making sure that I am taking time to be rooted in humilty; breathing in the calming gentle wind of the Holy Spirit; drinking from and plunging into the living waters that are provided and available to us whilest rooted in prayer and the Sacraments; and receiving the fire of God's Love in grateful receptivity, with my eyes fixed upon Jesus. I humbly hope this might be helpful to others in some small way, and wish everyone a very blessed New Year!
