The following article was written in reply to a mail, where a person was trying to prove spiritual studies as illogical and aimless. It establishes the equivalence of spirituality to experminental sciences.

As in case of experimental sciences, things are proved by experiments, so are they in spiritual sciences. The validity of the experiment is only accepted, if it can be repeatedly done at different places and time and it gives the same result. Therefore taking a simple example, Newton's laws are proved experimentally and we rightly accept them. But, in case I ask someone to get those results practically and demonstrate its success, it would take a lot of work and energy. To set  ideal conditions for the law to work (in limits of experimental error) practically and give right results will require tremendous amount of work, infact it will be virtually impossible to prove them again in absence of a lab and the extra sensitive apparatus it needs. But we still believe in it. WHY? (On the contrary, an amatuer on not getting the right result with his experiments may deny the law. But that is verily his own fault.) In exactly the same way, all the people in this group though know the law, are busy trying to fix up the apparatus, trying to set up the right conditions for the experiment to work, we all want to see God, we are not here for some intellectual debate, but we know we have been not able to set up the experimental conditions to do the same, like being
egoless, independent of desires, etc.

Therefore we have a theory at hand, which is logically convincing to us, it seems to give us the answer to our doubts about I, the universe and God. Intellectually it seems very correct. It being logical and convincing, and having at hand experiences of people who have proved these results, we tend to move in the same direction and see God.

Now for some hard talking. I don't understand, why people want to jump in case of spirituality, they don't treat it like any other science. Being a engineering student, when I start on a topic, I read all the previous work done on it and then go forth with application or further research, same is necessary for religion. There is no blind faith in it, but study, experimentation, further results or agreement with the past results. There is no need of any jumping and asking abstract questions in the beginning, there is no need to reinvent the wheel everytime, try to see how the previous theories have been, are they logically satisfactory, do they have some experimental results and what is the scope further. All I can say is to the common man, give spirituality a break, it is very much logical and scientific.
