Much has been written about this subject and probably more will be.  The purpose of life is unquestionable  and has to do with the origin and with  the meaning of life per se. We must live life as beings who feel,  think and have emotions by themselves and not  because others give us information, that may be very good and excellent but the fact is that we must reach the experience of living by ourselves, not by concepts but rather,  by our own experiences.  This of course does not offend since  is necessary to be, in order to  continue been.  It is not as if we were born from a factory, just perfect and without mistakes, since this is not possible.  Let's be realistic and let's not cast a shadow over our consciousness. Let's make a worthy scenario out of the consciousness,  where we have true, vital participation. Let's have shared in common and creative interests, where the noble  aspirations, mature in the context of a free opinion in order to approach seriously and with responsibility, the great diversity of subjects that life brings to us, almost every day.
Man, must be generous and cooperative and well instructed in the art of navigating by his own and other doctrines. Nevertheless,  life must be taken with great happiness and gratitude, so that we give back those  same feelings.  Life gives us so much that we must also participate in that universal communion, which is life.
And also,  to have many good intentions for everyone, sustained in the art of peace. There is no glory in violence, or in conflict.  The sensation of control and government by the power of  violence is a fleeting esteem that will  never obtain real happiness and will  tie man to look for a greater glory, a more  important promise, and then  man will  condemn himself  to look for what he will not be able to find, and he will keep sacrificing more and more his own life and the lives of  his loved ones. Instead of having and promoting peace, he will have a constant thirst of glory, which will take him to death  and destruction.
 Only,  when we are conscious that  the purpose of  life is to grow and to develop in Peace, we will realize that the Love of God is so vast and so noble, that wants for us to have Love and Peace.  To try to reach for the stars is to venture into crisis in which we will find self-destruction. To accept our limits is not to limit us, but is to live in accordance with reality.  The goal of man is Peace and in that Peace to have gratitude to his Creator. And a simple explanation is that man may have everything but without Peace, he will never enjoy not even the smallest experience of this  great all.
