my own interpretation of Mool Mantra would be as follows, I am not sure if this answers your question, but it is what Mool Mantra means to me
One creator present as one essence everywhere, whose name is the truth, architect of the universe, who has no fear, and no animosity, eternally consistent, eternally present, who is able to give direction, embrace these concepts and apply them, this essence entered into you at birth, remains with you your entire life, and is inside you as long as you exist, on death, this essence lives on, being shared with everything you have interacted with, either physically, emotionally and mentally.
Treat all life as you would treat yourself, be truthful and honest in all interaction, in this spirit of equality and honesty, plant your seeds, both in action, thought, and voice, to rid yourself of fear and animosity, but always be true to the part of Creator you have connected with already, have faith and trust that part of you, listen to it, it will never change, it cannot be swayed, it is the truth, apply these concepts to your life, plan your day with these concepts in mind, review your day by these concepts, remember this essence entered into you at birth, remains with you your entire life, and is inside you as long as you exist, on death, this essence lives on, being shared with everything you have interacted with, either physically, emotionally and mentally.
Although Luckyji has mentioned Love, I think there is a word that supersedes this, and that word is Truth, the very name of God, therefore God is the eternal Truth, not the convenient truth that one day hangs people, and the next day raises monuments to them, but the eternal truth, years ago, slavery was accepted, today it is frowned upon, then it was true, now it is false, all depending on culture, public opinion, etc etc, but the eternal truth rises above this, even now, some truths we accept, in future times, we will prove to be false, the truth does not change, it is always true, you just need the right lenses to see what is true and what is false.
The eternal truth, coupled with love is a hearty combination, it can conquer anything!
