In the end, you are the only one who may recognize yourself. You can be so different (everyone has a different horoscope) and you can be in such different situations (orphan in Brazil, mother with six children in Germany, old man in China) that there can be no instruction to self knowledge for everyone.
But at least there are universal structures such as the soul, the dynamic of a horoscope, the relationship mandala or the chakra system that can help in one's orientation and also in choosing a promising direction in which to search for one's source.
This book gives an overview of many of these possible approaches.
