I'll give an example, ‘a thought’. Can you see a thought or taste of thought or hear a thought with your ears? Can you smell the thought? And little you could have brain waves but can the brain wave tell you what the thought is? So, thoughts are invisible and they can't be necessarily directly verifiable through scientific instruments. But a single little thought could rule over a person's life more than all the things of this world. A thought when dictators invade countries and drop bombs and all of those things, the origin of that is a thought in their mind, right? So, we can understand the symptom by what we see outside, we can understand this person's really not thinking very good. But the thought itself is so subtle that it can't really be grasped. That psychology is a subtle science. But there's also a spiritual science.
