God's hand. One has to look. With one's thoughts and a lot of thinking to God.
I used to think I did all the thinking and that I was figuring things out. Some times, God's thoughts are in one's head.
From The Healing Power Of The Mind:
The Dharmasamgiti says: "People who have mental well-being, will hear Dharma from the sky, walls, and trees. For seekers whose minds are pure, teachings and instructions will appear just by their own wishes."
Keep the knowledge!
