If the intention was clear, the manifestation process is set into motion.
Time passes. It may seem nothing is happening.
Then suddenly you find yourself doing things that are actions to bring about your manifestation.
This is the deceptive part. As you're waiting for things to happen, your manifestation intention is so organic it starts to work without you recognizing that that's what's happening.
It's an interesting situation. You're looking on the outside for its appearance; meanwhile it's happening organically from the inside.
The challenge here is to pay attention, to stay aware when you start to take action, when ideas appear and you start to act on them. Understand them to be your manifestation starting to find its way into physical reality. Knowing that it's happening will help it appear. Notice how you feel and change inside accordingly; this also helps with the appearance of your manifestation.
It's a subtle process. However, once you know what it feels like, there is a wonderful sense of alignment within your own being and All That Is where your divine truth flows out of the very center of the Universe and you feel a part of the Universe and the whole Universe at the same time. It's quite wonderful.
