Firstly, you need not define such a thing, for in doing so immediately limits your understanding of its capacity to go beyond your current state of awareness. As your awareness expands, definition will become more difficult to relay the truth of the matter, which will go beyond words. Words will no longer be necessary, or adequate. For in truth all matters of life are so profound they are simply beyond words.
Within a definition, you begin to think and act in ways which throw things into a box, or throw them out of it because of a newly formed pre-conceived idea.
If in words I am to define such a thing as higher self, within my values, I would relay this as follows:
Higher self is that which you align to as being your most pure state, your grandest aspiration, your highest potential, your deepest love, your most divine concept of God, your most intimate relationship with yourself; that which is your spirit! Your spirit is all these things and more, for it is beyond my palette of paints to portray.
When you attempt to align yourself with your ‘higher self’ – which is in fact a misleading and somewhat disempowering mindset ( I will explain why in a minute ), you are attempting to attain the most profoundly intimate and complete relationship with who and what you truly are – that which is your spirit. Your spirit is the closest connection you will ever, ever experience to that which is God, for God IS through your spirit. There is no grander experience than this, and this is your gift, your very own relationship with God, through your spirit.
You will often hear ‘new age’ theories that insist your spirit must become something ‘more’ or join or ascend to something ‘more’ in order to know of God. It is within my knowing, and experience as a spirit guide that this is false, for not only do I know it is false but I await one to disprove me so who has access to absolute truth via the halls of learning beyond human state.
The mindset of seeking ‘higher self’ is misleading because you are enforcing a statement of reality that – that which you truly are (your spirit) is higher than you, and thus beyond your reach and creates concepts of lack, unworthiness, less-ness, SUFFERING. As long as you imagine yourself to be continuously seeking it, you will continue to experience separation from it by your own thoughts and aspirations. Thus, it is a game you choose to play. As is this so called new age ascension process. Your spirit is already God-ness (conscious-ness) and perfect, there is nothing greater to ascend to, only another form to embody it within. Another way to paint it.
If you already are your magnificent spirit, then why would you assume you have to seek it in order to be it? You cannot NOT be it, for it is you, always, in all ways. This is the understanding that the journey is over when the realization occurs that the destination has already been reached. You are already who you truly are, you need not seek it out, simply experience it in EVERY way: whether that way is in a positive way or a negative way – all is a part of your higher self. It is simply a matter of choosing in what way to experience that which you are – to embody it how you choose to.
Higher self can be simplified to simply – Self. Simply be your Self. It needs not be higher, simply closer in awareness. Your closer-Self. Simply be aware of yourself, always, in all ways. You are profound in every way, to be aware of this is to be Self-aware, and thus higher Self is transmuted simply to Self.
