Can there be something called spiritual science?

Can there be a concept called spiritual science? science as it is defined today in the mainstream world is as I said material explanations for material phenomena if you consider that definition then spiritual science is it's incompatible but if we consider science as a whole actually words their meanings are not fixed in dictionaries Newton did not identify himself as a scientist he identified himself as a natural philosopher the word scientist itself science said scientist came in the late 18th century so if today the word science most people they may study they may study science for 10-15 years and they won't even know that science actually means they look for material explanation of material phenomena so just think of science as a systematic body of acquiring knowledge so if we consider that generic understanding of science then as I said spiritual knowledge can be reasonable can be repeatable can be verified so the system of bhakti yoga that the Bhagavad Gita talks about it talks about different yogas congregation bhakti yoga it is reasonable in the sense that it makes sense if we understand systematically so it just as scientific theory does it if it makes sense it's reasonable so the basic question is they stand scrutiny of reason they're reasonable and then what it promises is repeatable it doesn't just promise us oh you will one day wake up and you'll see God well somebody may claim I have seen God but how will the rest of us know whether that person has seen God or not so the what the Bhagavad Gita focuses on is that we can see empirical transformation millions of people all over the world by practicing bhakti yoga have been able to have been able to break free from bad habits have been able to develop themselves spiritually have been able to say get rid of addictions get rid of anger and this has been objectively demonstrated so and this is something which is repeatable as I said thousands of people have experienced it and it is verifiable we ourselves can experience it so in terms of those criteria have been reasonable repeatable verifiable we can say that spirituality is also a science so thank you very much for your kind attention Hare Krishna.
