The Mool Mantar is about the nature of God as existence itself, Being, never moving, never changing indivisible consciousness. Being holy, It is all the good qualities. Being is forever Being, and Being is forever becoming with no beginning or end (destination). You will always Be (exist) and there will always be a dream. All genuine paths, long or short, are a means to the same one end - Self realization.
Real higher truth leads to less concepts (lighter shoulders), the opposite weighs one down with more concepts. One gains higer truth only to realize the wisdom of letting go of all concepts, (thinning out mental conditioning) to be more conscious of one's consciousness. Self realization is identity shift, from the individual mind ego body, to realizing your true self as an eternal spiritual formless Being.
