I've been looking for a resource just like this one. I have an ever growing collection of books about meditation. Some are formally presented and strictly adhere to a particular religious or dogmatic affiliation. Others, like Inner Journeys, are more fluid and easier to tailor to particular needs or situations as required.
Inner Journeys is one of the better books in this later category that I've come across. The author has included three sections of meditations: metaphysical, magical, and mystical. Each section contains about 20 different self-guided meditations. The majority of these exercises include visualization aspects. The entries themselves are extremely rich in detail which only adds to the effect. Often just reading through these meditations, I found myself transported to another place and experience.
I'm very pleased with Inner Journeys. With so many different mediations to choose from, it is easy to find the visualization that I might require on any given day. Furthermore, I found myself becoming more open and creative with my regular mediations.
