Yes, Lang. It is very difficult to overcome those views (ditthi) that have been in families for generations. But, hopefully, at least some will be able to spend time and see that Buddha’s description of the “wider world” must be true.
All religions are based on “lokiya concepts”.
– Those were all initiated by humans with the “nicca view” and “nicca sanna“. They try to come up with a permanent existence (in a heavenly realm).
Buddha Dhamma is a worldview discovered by the Buddha. His was not a conjecture; he saw all those realms and interacted with beings in those realms.
