Siva Baba (not to be confused with Sai Baba) gives a meditation for manifestation, using the mantra, “Ah.” Wayne Dyer describes this meditation in some of his books and talks as well. This is a simple meditation using the 7 chakras and making this very basic sound. If you watch this video on YouTube, you can see that Siva Baba has many other videos available, many having to do with manifestation techniques. I posted another one some months ago, the Sun-Moon meditation to transcend time.
