Everyone asks that if God gave us birth then why would He ask for worshiping him? The answer is no, He doesn't ask us to pray to him or worship him but to worship humanity. Just need to survive a fair life that doesn't include any fake things, criminal activities and hindrance to the people. After all God is there to judge you..We can easily buy 'Sirimad Bhagwat Gita' but how many of us read it hardly 1 %. I will recommend just go through once. It will take some 10 days if you give 15 minutes in a day. It doesn't give you any inspiration to do different work but will teach you how to work differently.
