Sometimes, the little voice in your head that you dialogue with all the time ... tells you to "ask for a sign". While that may work for some people - often nothing is shown - much to the dismay of those who may feel spiritually or emotionally abandoned. Don't fret! That silence itself has meaning. It's a cue to continue your journey exactly as it is.
If you try to step over your pre-programmed "timelines", it generally doesn't end well, so it is often best to just follow the yellow brick road to wherever your programming leads - that hopefully will take us all to OZ!
How do signs manifest? Since everything in our reality is pre-programmed - a sign will manifest whether you ask for it or not - and if you didn't ask you may overlook it completely. Then, of course, comes the guessing game of what it means and what you should do next. Reality, as we have come to understand it - is a loop of asking questions - then once those answers are given - they simply lead to more questions, on and on. I call it busywork. Don't strain your brain.
