Certainly the view seems similar to Mahayana and Taoist thinking. As a Phd in Philosophy this is exactly it. But as a biologist is there a way to alter peoples DNA issues to change the human being to greater health and mind? There needs research if there is not.
The WTM is not a religion teak. The FAQ section of the WTM’s website is very helpful and I recommend you read FAQ 6.1 where it addresses this very question, https://www.humancondition.com/wtm-faq-is-this-some-sort-of-religion/. In regard to changing our DNA to change human behaviour I recommend you read FAQ 1.2 (https://www.humancondition.com/wtm-faq-how-does-science-explain-the-human-condition/). You will see as you digest this explanation further that it is not our DNA that we need to look to, but understanding the human mind. To quote from FAQ 1.2, “Humans have suffered not from the genetic-opportunism-based, non-psychological animal condition, but the conscious-mind-based, psychologically troubled human condition.” It is this longed-for breakthrough explanation of the human condition that biologist Jeremy Griffith has found and it opens up an immensely exciting and transformed world!
