Spiritual knowledge is a regular science. Just as two and two make four, similarly everything is clean and obvious here also and there is no scope for any kind of modification or change in that.
I have written a book on the Naam, or Word, or Kalma, in which quotations from different scriptures are given; and also 'The crown of life' which is a comparative study of the different systems of yoga. Apart from these I have written books on Saints and their teachings, and other books.
There is intentionally no author's right reserved for the publication of these, so that these teachings which are a gift of nature may easily reach everyone.
