I wrote a book and I have a conceptual approach. I have my own understanding, on this topic and also philosophically and spiritually contained. How may I publish as a research paper and post it on research gate. Thanks.
See this help page ("How to add research") for instructions how to add texts to ResearchGate: https://help.researchgate.net/hc/en-us/articles/14293005132305. However, this will not be a publication, see "Is ResearchGate a publisher?" in https://help.researchgate.net/hc/en-us/articles/14292596164753.
