The Inner Voice will counsel you regarding simple things that are valuable to know what to do, but do not represent great decisions before you.
You have to be successful with the simpler things first and build up your strength here.
The inner voice just gives directions. And amazingly this inner voice is speaking to you far more then you are aware of, but your mind is so caught up in the outside in your own thinking, and in being stimulated and driven and busy that you cannot hear or feel this inner voice.
People often deny the experience of this [inner voice] until something really big happens in their life and they have to make a huge decision. And they hear that there is Knowledge within them, and so they try to make a huge decision with it. But they have not built the bridge between their thinking, surface mind and their deeper mind of Knowledge.
