The manifestation process is a path to consciousness. The manifestation process is not just a matter of showing everyone how clever you are at accumulating more and more stuff. More importantly, it’s a matter of becoming aware of how and why you do what you do during the process, so that truth and integrity are your guiding forces.
Let your conscience be your guide.
By rising to the challenge of becoming more conscious, you set in motion the manifestation of your truest and highest soul potential. Then it won’t matter if you get the stuff you want or not.
Putting a desire for material possessions before a focus on developing your consciousness, and thus ignoring your conscience, is another reason why things go wrong with your manifestation process.
