From Likutei Halachos from Reb Nossan Breslover. A person is hefker (ownerless) until they accept the Torah in their own life. Some Breslovers should realize that you can be ish kodesh (holy Jew) without hefkaros. The entire world is a cemetary filled with tribulations. Hefker means you are no longer claimed by Hashem. Need to take a stand in life. Need to do the ratzon (will) of Hashem.
