(personalPersonal belief)
1) If you want to achieve or gain something in this way, actually you are invoking the universe to give it to you. And invoking/asking from anyone other than Allah is shirk. The following verses state about those who do this:
وَمَنْ أَضَلُّ مِمَّن يَدْعُو مِن دُونِ اللَّهِ مَن لَّا يَسْتَجِيبُ لَهُ إِلَىٰ يَوْمِ الْقِيَامَةِ وَهُمْ عَن دُعَائِهِمْ غَافِلُونَ
And who is more astray than he who invokes besides Allah those who will not respond to him until the Day of Resurrection, and they, of their invocation, are unaware.[46:5]
ذَٰلِكُم بِأَنَّهُ إِذَا دُعِيَ اللَّهُ وَحْدَهُ كَفَرْتُمْ ۖ وَإِن يُشْرَكْ بِهِ تُؤْمِنُوا ۚ فَالْحُكْمُ لِلَّهِ الْعَلِيِّ الْكَبِيرِ
[They will be told], "That is because, when Allah was called upon alone, you disbelieved; but if others were associated with Him, you believed. So the judgement is with Allah , the Most High, the Grand." [40:12]
لَهُ دَعْوَةُ الْحَقِّ ۖ وَالَّذِينَ يَدْعُونَ مِن دُونِهِ لَا يَسْتَجِيبُونَ لَهُم بِشَيْءٍ إِلَّا كَبَاسِطِ كَفَّيْهِ إِلَى الْمَاءِ لِيَبْلُغَ فَاهُ وَمَا هُوَ بِبَالِغِهِ ۚ وَمَا دُعَاءُ الْكَافِرِينَ إِلَّا فِي ضَلَالٍ
To Him [alone] is the supplication of truth. And those they call upon besides Him do not respond to them with a thing, except as one who stretches his hands toward water [from afar, calling it] to reach his mouth, but it will not reach it [thus]. And the supplication of the disbelievers is not but in error [i.e. futility]. [13:14]
2) The universe is a creature of Allah and should not be supposed to do what just our creator, Allah, is able to do. Again it's called shirk:
أَيُشْرِكُونَ مَا لَا يَخْلُقُ شَيْئًا وَهُمْ يُخْلَقُونَ
Do they associate with Him those who create nothing and they are [themselves] created? [7:191]
3) Allah has warned us not to be a Mushrik believer! So it's not that strange when you see some Muslims believe and obey this law of attraction:
وَمَا يُؤْمِنُ أَكْثَرُهُم بِاللَّهِ إِلَّا وَهُم مُّشْرِكُونَ
And most of them believe not in Allah except while they associate others with Him. [12:106]
4) And as the last word, when Allah has promised to respond our invocations, why not to call himself?
وَإِذَا سَأَلَكَ عِبَادِي عَنِّي فَإِنِّي قَرِيبٌ ۖ أُجِيبُ دَعْوَةَ الدَّاعِ إِذَا دَعَانِ ۖ فَلْيَسْتَجِيبُوا لِي وَلْيُؤْمِنُوا بِي لَعَلَّهُمْ يَرْشُدُونَ
And when My servants ask you, [O Muhammad], concerning Me - indeed I am near. I respond to the invocation of the supplicant when he calls upon Me. So let them respond to Me [by obedience] and believe in Me that they may be [rightly] guided. [2:186]
وَقَالَ رَبُّكُمُ ادْعُونِي أَسْتَجِبْ لَكُمْ ۚ إِنَّ الَّذِينَ يَسْتَكْبِرُونَ عَنْ عِبَادَتِي سَيَدْخُلُونَ جَهَنَّمَ دَاخِرِينَ
And your Lord says, "Call upon Me; I will respond to you." Indeed, those who disdain My worship will enter Hell [rendered] contemptible.[40:60]
