It’s important to differentiate between the approach and content of science.
The approach of science is mostly common sense guidelines for exploring and investigating reality and life. And it’s very applicable for exploring who and what we are, and the nature of reality as it appears to us. In other words, it’s very applicable to our exploration of – what some may call – spirituality.
The content or product of science is different. This is what we think we know and it changes over time and somewhat across cultures. What we think we know today may be outdated tomorrow. Even our worldview and our most basic assumptions about reality changes.
