This is a very good point. I believe that spiritual awakening doesn't necessarily bring more control into your life, but provides you with the fortitude to allow whatever happens in your life (whether bad or good) to flow with you. So you can endure bad things, you can also enjoy good fortune, but without being tied to it.
Alan Watts (my personal favourite spiritual teacher) says that the idea of letting go of attachment isn't necessarily about "not letting yourself feel things or care about things" but more "not developing hangups about things". So if trauma happens, you work through it, you grieve, you feel pain, but you don't get stuck in it and have it define your life forever. If luck happens, you enjoy it, but you don't try and cling too hard to it. If love happens, you feel it to the full but don't try and control the ones you love. Etc. You flow with the universe rather than try and stand still.
As for manifestation, I believe in the law of attraction in the sense of the subconscious learning to notice positive patterns vs negative patterns. That doesn't mean however that some freak accident or terrorist attack or something won't happen to you, but overall your experiences in life will turn towards positive and open experiences, rather than fearful, self defeating and negative experiences. I have a friend who sees everything as evidence of persecution, sexism and reasons to hate herself. She is only seeing part of the picture however, her subconscious is seeking out evidence that confirms her beliefs about herself (that she will never succeed, that she will never recover, that no one will ever love her) and finding that evidence, ignoring evidence to the contrary.
The other side of manifestation is about becoming the person you want to be, including becoming the mindset you wish to have. That takes a long time, but over time (with the help of therapy if that's what you need) it can definitely happen. I manifested a confident, beautiful, mentally healthy and successful version of myself because I created an alter ego that was all of those things, and became that version of myself over a period of about 10 years.
The biggest takeaway for me, is the idea of abundance mindset. Not in the sense of a televangelist saying "give me money and God will give you more in return" but more, feeling that my life as it is right now, is abundant in so many things purely by virtue of being alive. Life is beautiful, my loved ones are dear to me, nature is miraculous, food is delicious, I can give myself beautiful visions of imagination, listen to music, give myself orgasms etc
Success via an abundance mindset isn't necessarily that "you will earn millions by manifesting it" but that you may realise that everything you needed (for fulfilment, I'm not talking basic needs like food and shelter and safety from violence) was inside you all along. And thus everything else, success, wealth, power - they can be pursued out of a sense of play, not out of a sense of fear. You do what you truly want to do. If that makes sense.
