What does "he finds his truth" mean in Pope Benedict's Caritas in Veritate?

While I was reading [Caritas in Veritate](http://w2.vatican.va/content/benedict-xvi/en/encyclicals/documents/hf_ben-xvi_enc_20090629_caritas-in-veritate.html) , an encyclical letter by Pope Emeritus Benedict XVI, I found this fragment: > Love — caritas — is an extraordinary force which leads people to opt for courageous and generous engagement in the field of justice and peace. It is a force that has its origin in God, Eternal Love and Absolute Truth. Each person finds his good by adherence to God's plan for him, in order to realize it fully: in this plan, **he finds his truth**, and through adherence to this truth he becomes free (cf. Jn 8:32). What does it mean to find one's truth? To what truth was Pope Benedict XVI alluding in that fragment?
