Sharing Life and resources

When we are living here, eating here, healthy here, there should be some purpose behind allowing us to be in this arena by Lord God. What may be that objective? without objective how the clever God allows us to waste away the valuable resources on this earth? Ofcourse it is not easy to define the purpose of life in simple terms, but we can simplify the purpose of life into few lines.
Loka samastha sukhino bhavanthu is the sanskrit dictum which means "all the world should be happy ". We live in such harmonious way that we do not disturb the peace of the world with our living and behaviour. More than this, the second step is we should help fellow living beings to be happy, to the extent possible.
By sharing the resources you have, when needed , with others to the extent possible, it gives meaning to your life. My Guru told a wonderful small story. Once a traveller is sleeping on the outside verandah of a hut,after setting dark. The place was just sufficient to lay him there. Meanwhile rain started and two more travellers came running to that shaded place, for protection from rain. So, this good samaritan invited them to his small place and he sat up and offered the remaining place to others. Thus he shared his place with them. The rain increased and three more passengers also came there, drenching and requested place. Then he got up, stood on the floor and invited them in telling to them " please come, we share this place" . Thus he shared the little place he got with fellow human beings, in case of need and this is sharing of life , resources with others. This pleases Lord God.
