In Indian Philosophy there is some thing called "Nethi, Nethi..." (Spelling may not be correct). its meaning is "this is not, this is not...". They use this philosophical term to describe God. That is God (Super power is so big) and all encompassing, so that we cannot understand that existence fully. God is everywere and in everything we can see God (Super Power). So ordinary human being may confuse the ordinary things of the world as God (Super Power) and may attach themselves on that worldly things, which may have some qualities of God. eg: God is not air, even though air can reach every were; God is not water, even though water can purify things; God is not ocian, even though it can be the dwelling place of many creatures; God is not sun, even though sun illumine everything. NOW YOU MAY BE THINKING WHY ON EARTH I AM TALKING ABOUT GOD (SUPER POWER) WHEN YOU ASKED ABOUT SPIRITUALITY. The reason is very simple. Spirituality like God (Super Power) is so immessurable, it is not possible to define spirituality. The method to understand spirituality is to use "Nethi" Philosophy. But before we go to that, the very word spirituality means "something related to Spirit". and in Individual case it is something related to once own spirit.
Now here we have to see what exactly this spirituality is not, but may be thought of the sings of sipirituality. We have to understand why a particualar thing may include some aspects of spirituality, but may not be the whole of spirituality. HERE AGAIN WE HAVE TO UNDERSTAND ANOTHER ASPECT ABOUT LOGICAL CONCLUSION. IF I TAKE A PARTICULAR SUBJECT AND IF I ACTUALLY EXAGERATE IT, WILL IT STILL BE SIGN OF SPIRITUALITY - IF NOT THEN THAT PARTICULAR SUBJECT MAY HAVE SOME QUALITIES OF SPIRITUALITY, BUT MAY NOT BE THE REAL SPIRITUALITY. Now combaining this Logical conclusion method and Nethi philosophical method you wil be able to know wether particular aspect of behaviour is spirituality. LET US ANALYSE WITH EXAMPLE. Love: is that spirituality. at the first site it is. And to be spiritual love should be there. But when we exagerate love, love can go to the level of possesiveness, or love of inordinate things...etc. So love without balace is not spirituality. Hatred. Is that spirituality. At the first site it may seem that hatredness toward unholy things is sign of spirituality, but when hatredness extend to jelousiness it is not spiritualtiy. Rituals: sign of spirituality, but adherence to rituals without having human heart is not spirituality. patience: sign of spirituality, but patience which stop a person reacting to evil is not spirituality. SO MAY BE IN A WAY WE CAN DEFINE THAT SPIRITUALITY IS A KIND OF BALANCE, A MIDDLE PATH. THE MOMENT A PERSON LOSES THIS BALANCE, THE MIDDLE PATH THE PERSON GOES OUT OF THE WAY OF SPIRITUALITY
