I think all kinds of meanings in life transcend your self. They're linked to other generations of people around us, to our children and our family. We're passing on something of ourselves to others. I feel that's what makes our life full of meaning.
To care of another individual means to know and to experience the other as fully as possible.
A sense of life meaning ensues but cannot be deliberately pursued: life meaning is always a derivative phenomenon that materializes when we have transcended ourselves, when we have forgotten ourselves and become absorbed in someone (or something) outside ourselves
To love means to be actively concerned for the life and the growth of another.
