For Espiritismo, Mediumship and Spiritualism, the best primer I have read is Ancestor Paths, by Oba Ilari Aladokun.
Within these chapters, the author and Priestess Ilari presents a concise guide on working and honoring the spirits that already walk with you, rooted in practices of Espiritismo, Spiritualism, and Personal as well as Group Mediumship.
The book presents a view of Espiritismo that highlights it’s identity as a both a Cuban rooted spiritual tradition, but also a well traveled one that moves with the cultures and people it takes root in.
North American Table Spiritualism can learn much from the more holistic approach authors and practitioners of Espiritismo take towards the spirit worlds.
As Espiritismo travels with the Cuban Diaspora and converges with North American Spiritualism, Chinese Folk Religions, European Witchcraft, Black American Rootwork etc, the courts of spirits become enriched, and in turn the practices and spirits Espiritismo absorbs opens doors to new ways of spirit communication within these other cultural practices it interacts with.
Through Espiritismo and Spiritualism, I have been able to reconnect with my guides and Ancestors, not just with the means I learned growing up in my own culture, but also through the cross cultural approach taken by Espiritismo and Spiritualism.
I am not just Chinese, but a Chinese Canadian, living in a city covered in a multicultural tableau.
I have Chinese guides and ancestors. I have Hindu ones. I have Black American rooted spirits. I have European Spirits. All a part of my spiritual tableau for different reasons and because of the different routes my life has taken.
Spiritualism, and more importantly techniques in Espiritismo, provided me with a manner of honoring and communing with all the good, elevated spirits that walk with me. This book was instrumental in helping me do that.
I feel one of my ways of giving back is to spread a helpful, primary source like this book and author to those who feel lost in Spirit, and who may not have access to more experienced mediums.
Hopefully this book will help you as it has me, in the development of my personal path in the world of Spirit.
