Others may seem to be more evolved or enlightened because they think of themselves as an immortal soul or a divine spirit. But do they really know themselves or have they just added some spiritual-sounding concepts to the content of their mind? Knowing yourself goes much deeper than just a set of beliefs or ideas. Spiritual beliefs and ideas are at best helpful pointers, but in themselves rarely have the power to dislodge the more firmly established core concepts on who you think you are, which is part of the conditioning of the human mind.
Knowing yourself deeply then has nothing to do with whatever ideas are floating around in your mind. Knowing yourself is to be rooted in Being, instead of being lost in your mind.
