God & Myself, Prayer ?

Why should we pray ? This is a question Haunting me for the past 8 years and still feel there is no perfect answer for that question. I always try to explain every thing by analyzing wht is happening to me and why it has happend instead of being a mirror and reflecting others thoughts & thus i some how managed to find few reasons for praying and i would like to sum it up as follows.. When I say I belive in GOD it means i Belive in the Unexplained Energy inside me which makes me,every one & the Universe to live. When ever iam happy i feel there is no need to think about GOD and when ever I’m sad I always go to the temple and seek for GOD. That’s how i started my faith with god and even when I tried to pray diff god i felt my prayers are answered. This made me realize that GOD is beyond the Religious Mask. Then by reading JKrishnamurthy's speech, Swami Vivekanadha, The Holy Geetha I was surprised to see that we should not ask god for some thing during the prayer instead we should leave every thing to his hands and just thanks him for wht ever he has done. This was very hard to practice at first but then when i re visited all my prayers i found its very silly to see myself praying so hard for some thing which was the most important thing in my life but after some time it become least important to me like passing exams, getting job, getting well from a wound, fever, praying for my dear and loved ones etc. After putting lot of thoughts i could see GOD was not waiting for my prayers, GOD is just doing his duty even if u don't pray or pray it will not affect him he just continues to do wht he intend to do like how a Beautiful Flower Spread its sent of love to who ever comes to its vicinity even if tht person praise the flower or curse it or plucks it out of the branch it stills shows the same love and affection to all. So god is not operated by the prayers u do ,Then why over these thousand years each religion has followed or en forced some thing called as prayers? Why every religion followed a diff style for prayer and diff chanting and diff days for the same cause ?When i tried to pray every god in the religion by strictly following the instructions given by the religion i first felt that I am pleasing the god by controlling my self to the path which he wanted. But over a period of time i found tht i lost the happiness in praying god when I concentrate more on the way in which I pray god say rushing to the temple on festival day, Trying to find campor and if I couldn't find I feel bad, If the coconut broken b4 god is not proper then my concentration went to why the coconut was not in shape than praying the god, If i miss to attend the Mass in church then felt bad that all my prayers which I have done so far is gone etc...Then on thinking over and over about this i found out that GOD is not happy when u follow the instructions its we who feel or believe that he will feel. Then wht is this Prayer ? Wht should i do when i stand b4 god ? Wht is the enlighten or the feeling of high spirituality I get when I stand before the Gods Idol ? why I tend to forget the whole world when I’m in the prayer and put myself before god ?Should i need to praise God in all prayers and don't beg for my benefits ?or should i need to beg for wht i want and then do a business deal with him tht I will do other things if u full fill my wants and needs ?will god punish if i fail to do those things ?This become a million dollar question and obviously there are no Vivekanadha or Ramakrishna Paramansha or any Saint is reachable to me to give answers. The fact is even they can't give the answer for these questions because the answer for all these question should be realized from ones self consciousness and all those great saints can only show the path or guide to realize the answers. So when i stand before the Idol of Lord Krishna I could see The un explained energy which is inside my heart and stopping me form hurting others, instructing me to help some one for no return, try to spread smyle in others life, eliminating the fear and anger from mind. That is the Idol Man or That un explained energy is the complete or Perfect self conscious person inside me and unfortunately tht person only lives for a short time. Cuzz I’m not a saint and i also do things to hurt others, being selfish and other things. So when i stand before the god and ask for strength i Feel i just realize the God inside me standing in front of me and I’m giving instructions to myself which makes me grow stronger and more proper to attain ultimate happiness. So i felt prayer is nothing but expressing your feelings of happiness, sadness, weakness to the greatest Belief of your life and in doing it u achieve ultimate peace. Strength and faith in your life to motivate your self for a better life .
