One of the problems of living at the present time is that not only is it a time of materialism and atheism but that when individuals do turn to the spiritual they often take large chunks of the materialistic, atheistic culture in which they grew up with them. They retain inbuilt assumptions of the secular world. Nowadays this is usually (though not always) in the form of leftist ideology which most people don't realise is formed from a rejection of God and religion and an attempt to supplement these spiritual realities with an earthly simulacrum of them with the earthly human being at the centre. This means that their version of spirituality is a post-Enlightenment, post-French Revolution version, both of which were actively anti-spiritual. Such people are left with a form of spirituality which is focussed on humanity rather than God which gives them a kind of cognitive dissonance. As I said in a previous post, we need to see the spiritual in its own terms and from its own perspective not in our worldly, human terms. And yet this latter is precisely what so many people now do. They see the spiritual as something that should operate to benefit the human being as the human being is here and now in its fallen state. This effectively means you can have spirituality without repentance which is a sad distortion of the truth.
I have heard people claim that spiritual feelings are natural human feelings and that you can pursue spiritual values and believe in transcendence, love, peace, wisdom etc without worrying about God or Christ or the afterlife or anything religious. They are mistaken. Your feelings are not truth. They might be based on truth (they might be based on a lot of other things too) but they are still just your personal feelings. You must go beyond them to their real source. And their real source, if they are authentic and not just wishy-washy indulgences, is God. You cannot separate the fruit from the tree and if you do so the fruit will quickly rot. That is the problem. Unless you root your spiritual feelings in their source they will remain shallow and then decay and become caricatures of themselves, pale copies of reality, things that you feel you feel but don't really feel.
Modern forms of spirituality are often just forms of psychological therapy and ignore the spiritual fundamentals of repentance and belief in God. You are not a child of God now simply by believing yourself to be so. The bridge to that state remains narrow, the sacrifice demanded remains extreme for it is that of your worldly self. That self as it is cannot be spiritualised which is a common error made by those whose idea of spirituality is their feelings. It must be given to God. Not as a theory but in reality, and for this to be real demands complete acceptance of God as a real being not just some vague, amorphous abstraction that you keep at a safe distance.
You might think you can have spirituality without God but that is a trick of the devil. The only valid approach that has ever tried that is the Buddhist one which is why Buddhism is popular among the spiritually deracinated these days. But two things need to be understood. Firstly, Buddhism was traditionally always a monastic religion, and I emphasise both words. Buddhism may not have been theistic but it still demanded an intense religious approach not a secular one. And two, for all the later attempts to compensate for this, Buddhism is essentially a creation-rejecting spirituality which denies the goodness of the self. But God had a purpose in creation. His aim was not to return to the unformed state but to bring the beauty of matter into harmony with the truth of spirit and make something new.
But anyway, contemporary secular spirituality often owes more to Jung than the Buddha, and while Jung is praised for bringing the spiritual to the psychological you could equally well say he did the opposite and brought the spiritual down to the psychological level thereby secularising it and robbing it of its spiritual truth.
