Of all the places you have listed Philosophy is the one where we come and discuss matte relating to all the rest. This is where we see that all the places listed are what constitutes life, i.e. family, friends, religion and works is what life is made up of. The right place to find the meanings of life is not any one of these but a place put together, and thus formed, by you for instance. A place that is your heart, your mind, your spirit, the entirety of your being.
The purpose of you being alive is to find the truth through all these situations of life, and the meaning of life, to live up to it, to accept is, as it were there for the reason of you being there, now it is there by the way of you being alive. The truth is the golden thread that connects all things together and you to the togetherness of all things, and everything to the absolute truth.
