There are so many books, videos, and Co. out there about this fascinating topic. Recently I listened to an interview with Dr. James Doty about manifestation. He is a clinical professor of neurosurgery at Stanford University and I enjoyed hearing his take as a neuroscientist. A very humble and highly intelligent man. Wonderful interview; I'll include the link below in case you want to have a listen.
I saw the video very inspiring and informative also, I have not yet completed the full video, half an hour is remaining, watching it in parts, but it's interesting. Thanx for sharing.
Life is a big mystery and the knowledge of life we keep unfolding them as we keep progressing.
