the main purpoe of life is to realize god.this privileege the lord has bestowed only on human beings,the human body is the top rung of the ladder of creation.from here we can either drop down to lower species,or we can go back to the father and escape from the cycle of birth and death.everything else we have been getting every time we have come into this world,in any form,in any species.but the privilege of going back to the father can be achieved only in the human life.so we should always be mindful of our destination and try to follotthe spiritual path which leads us back to him.while working out out destiny,our karmic accounts or adjustments-out other duties,responsibilities-we should not forget the end and purpose for which we have come into this world.
